93-547: The FidoNet system was based on several small interacting programs, only one of which needed to be ported to support other BBS software. FidoNet was one of the few networks that was supported by almost all BBS software, as well as a number of non-BBS online services . This modular construction also allowed FidoNet to easily upgrade to new data compression systems, which was important in an era using modem -based communications over telephone links with high long-distance calling charges. The rapid improvement in modem speeds during

186-512: A tosser put them back into the new system's forums. Echomail was so popular that for many users, Echomail was the FidoNet. Private person-to-person Netmail was relatively rare. FidoNet is politically organized into a tree structure, with different parts of the tree electing their respective coordinators. The FidoNet hierarchy consists of zones , regions , networks , nodes and points broken down more-or-less geographically. The highest level

279-456: A PC without the need for actual porting (instead relying on the common porting of individual component libraries ). Porting arcade games to home systems with inferior hardware was difficult. The ported version of Pac-Man for the Atari 2600 omitted many of the visual features of the original game to compensate for the lack of ROM space and the hardware struggled when multiple ghosts appeared on

372-405: A cheaper solution). The number of significantly different CPUs and operating systems used on the desktop today is much smaller than in the past. The dominance of the x86 architecture means that most desktop software is never ported to a different CPU. In that same market, the choice of operating systems has effectively been reduced to three: Microsoft Windows , macOS , and Linux . However, in

465-475: A computer communicates with another device such as a modem , the two devices will signal each other that they are switched on and ready to work, as well as to agree to which protocols are being used. Handshaking can negotiate parameters that are acceptable to equipment and systems at both ends of the communication channel, including information transfer rate , coding alphabet , parity , interrupt procedure, and other protocol or hardware features. Handshaking

558-408: A connection is established are in fact the sounds of modems at both ends engaging in a handshaking procedure; once the procedure is completed, the speaker might be silenced, depending on the settings of operating system or the application controlling the modem. This frequently used term describes the use of RTS and CTS signals over a serial interconnection. It is, however, not quite correct; it's not

651-399: A home console with the same specifications. This allowed arcade perfect games to be played at home. A "console port" is a game that was originally made for a console before an identical version is created which can be played on a personal computer . This term has been widely used by the gaming community. The process of porting a game from a console to a PC is often regarded negatively due to

744-587: A host BBS system. Point mail was delivered to a selected host as if it was addressed to a user on that machine, but then re-packaged into a packet for the point to pick up on-demand. The complete addressing format was now zone:net/node.point , so a real example might be Bob Smith@1:250/250.10 . Points were widely used only for a short time, the introduction of offline reader systems filled this role with systems that were much easier to use. Points remain in use to this day but are less popular than when they were introduced. FidoNet supported file attachments from even

837-501: A long-distance problem that no longer existed. The FidoNet nodelist started shrinking, especially in areas with a widespread availability of internet connections. This downward trend continues but has levelled out at approximately 2,500 nodes. FidoNet remains popular in areas where Internet access is difficult to come by, or expensive. Around 2014, a retro movement led to a slow increase in internet-connected BBS and nodes. Telnet, rlogin, and SSH are being used between systems. This means

930-447: A machine independent intermediate code in order to enhance portability of the compiler and minimize design efforts. The intermediate language defines a virtual machine that can execute all programs written in the intermediate language (a machine is defined by its language and vice versa). The intermediate code instructions are translated into equivalent machine code sequences by a code generator to create executable code . It

1023-432: A netmail message to a special system, Node 51. The message contained various required contact information. If this message was transmitted successfully, it ensured that at least some of the system was working properly. The nodelist team would then reply with another netmail message back to the system in question, containing the assigned node number. If delivery succeeded, the system was considered to be working properly, and it

1116-614: A new bulletin board system that would emerge as Fido BBS. It was called "Fido" because the assorted hardware together was "a real mongrel". Jennings set up the system in San Francisco sometime in early 1984. Another early user was John Madill, who was trying to set up a similar system in Baltimore on his Rainbow 100 . Fido started spreading to new systems, and Jennings eventually started keeping an informal list of their phone numbers, with Jennings becoming #1 and Madill #2. Jennings released

1209-439: A policy was not always feasible; Bunten stated that "M.U.L.E. can't be done for an Apple", and that the non-Atari versions of The Seven Cities of Gold were inferior. Compute!'s Gazette wrote in 1986 that when porting from Atari to Commodore the original was usually superior. The latter's games' quality improved when developers began creating new software for it in late 1983, the magazine stated. In porting arcade games ,

1302-715: A store and forward public message system similar to Usenet , but based on, and hosted by, the FidoNet system. The first such echomail forum was one created by the Dallas area sysops to discuss business, known as SYSOP. Another called TECH soon followed. Several public echos soon followed, including GAYNET and CLANG. These spawned hundreds of new echos, and led to the creation of the Echomail Conference List (Echolist) by Thomas Kenny in January 1987. Echomail produced world-spanning shared forums, and its traffic volume quickly surpassed

1395-415: A true form of handshaking, and is better described as flow control . In mobile device chargers offering special quick-charge abilities to supported devices, the charging process will switch up to a higher output voltage for increased power transfer. But this could cause serious damage to an unsupported device or even result in a fire. It is therefore very important for the device and charger to first perform

1488-431: A unique set of addresses, avoiding potential routing conflicts and ambiguities for systems that belonged to more than one network. FidoNet addresses explicitly consist of a zone number, a network number (or region number), and a node number. They are written in the form Zone:Network/Node . The FidoNet structure also allows for semantic designation of region, host, and hub status for particular nodes, but this status

1581-485: A zero. Systems running existing versions of the software already ignored the fields containing the new addressing, so they would continue to work as before; when noticing a message addressed to another node they would look it up and call that system. Newer systems would recognize the network number and instead deliver that message to the network host. To ensure backward compatibility, existing systems retained their original node numbers through this period. A huge advantage of

1674-549: Is a technique of communication between two entities. However, within TCP/IP RFCs, the term "handshake" is most commonly used to reference the TCP three-way handshake. For example, the term "handshake" is not present in RFCs covering FTP or SMTP. One exception is Transport Layer Security, TLS, setup, FTP RFC 4217. In place of the term "handshake", FTP RFC 3659 substitutes the term "conversation" for

1767-443: Is also possible to skip the generation of machine code by actually implementing an interpreter or JIT for the virtual machine. The use of intermediate code enhances portability of the compiler, because only the machine dependent code (the interpreter or the code generator) of the compiler itself needs to be ported to the target machine. The remainder of the compiler can be imported as intermediate code and then further processed by

1860-480: Is also used when software/hardware is changed to make them usable in different environments. Software is portable when the cost of porting it to a new platform is significantly less than the cost of writing it from scratch. The lower the cost of porting software relative to its implementation cost, the more portable it is said to be. The term "port" is derived from the Latin portāre , meaning "to carry". When code

1953-403: Is less complex and therefore easier to port than a code generator, because it is not able to do code optimizations due to its limited view of the program code (it only sees one instruction at a time, and users need a sequence to do optimization). Some interpreters are extremely easy to port, because they only make minimal assumptions about the instruction set of the underlying hardware. As a result,

2046-479: Is not compatible with a particular operating system or architecture , the code must be "carried" to the new system. The term is not generally applied to the process of adapting software to run with less memory on the same CPU and operating system. Software developers often claim that the software they write is portable , meaning that little effort is needed to adapt it to a new environment. The amount of effort actually needed depends on several factors, including

2139-510: Is not directly indicated by the main address. For example, consider a node located in Tulsa, Oklahoma , United States with an assigned node number is 918, located in Zone 1 (North America), Region 19, and Network 170. The full FidoNet address for this system would be 1:170/918 . The region was used for administrative purposes, and was only part of the address if the node was listed directly underneath

2232-431: Is that of dial-up modems , which typically negotiate communication parameters for a brief period when a connection is first established, and there after use those parameters to provide optimal information transfer over the channel as a function of its quality and capacity. The "squealing" (which is actually a sound that changes in pitch 100 times every second) noises made by some modems with speaker output immediately after

2325-432: Is the zone, which is largely continent-based: Each zone is broken down into regions, which are broken down into nets, which consist of individual nodes. Zones 7-4095 are used for othernets ; groupings of nodes that use Fido-compatible software to carry their own independent message areas without being in any way controlled by FidoNet's political structure. Using un-used zone numbers would ensure that each network would have

2418-511: The Atari VCS became the console's killer app despite its differences, while the later Pac-Man port was notorious for its deviations from the arcade version. Arcade-accurate games became more prevalent starting in the 1990s as home consoles caught up to the power of arcade systems. Notably, the Neo Geo system from SNK , which was introduced as a multi-game arcade system, would also be offered as

2511-468: The Commodore 64 world, and AlterNet . Late in the evolution of the FidoNet system, there was a proposal to allow mail (but not forum messages) from these systems to switch into the FidoNet structure. This was not adopted, and the rapid rise of the internet made this superfluous as these networks rapidly added internet exchange, which acted as a lingua franca . FidoNet started in 1984 and listed 100 nodes by

2604-745: The GNU Compiler Collection , which provides consistent programming languages on different platforms, and Autotools , which automates the detection of minor variations in the environment and adapts the software accordingly before compilation. The compilers for some high-level programming languages (e.g. Eiffel , Esterel ) gain portability by outputting source code in another high level intermediate language (such as C ) for which compilers for many platforms are generally available. Two activities related to (but distinct from) porting are emulating and cross-compiling . Instead of translating directly into machine code , modern compilers translate to

2697-444: The attachment of a single file to every message. This led to a series of piggyback protocols that built additional features onto FidoNet by passing information back and forth as file attachments. These included the automated distribution of files and transmission of data for inter-BBS games. By far the most commonly used of these piggyback protocols was Echomail , public discussions similar to Usenet newsgroups in nature. Echomail

2790-496: The embedded systems and mobile markets, portability remains a significant issue, with the ARM being a widely used alternative. International standards, such as those promulgated by the ISO , greatly facilitate porting by specifying details of the computing environment in a way that helps reduce differences between different standards-conforming platforms . Writing software that stays within

2883-556: The 15 systems running by the start of June 1984, 5 of them were in St. Louis. A user on Jennings's system in San Francisco that addressed emails to different systems in St. Louis would cause calls to be made to each of those BBSes in turn. In the United States, local calls were normally free, and in most other countries were charged at a low rate. Additionally, the initial call setup, generally

2976-502: The Apple rewrites?" the audience shouted "No!" Garriott responded, "[otherwise] the Apple version will never get done. From a publisher's point of view that's not money wise". Others worked differently. Ozark Softscape , for example, wrote M.U.L.E. for the Atari first because it preferred to develop for the most advanced computers, removing or altering features as necessary during porting. Such

3069-709: The CBBS onto this machine. The Rainbow contained two processors , an Intel 8088 and a Zilog Z80 , allowing it to run both MS-DOS and CP/M , with the BBS running on the latter. When the machine arrived, they learned that the Z80 side had no access to the I/O ports , so CBBS could not communicate with a modem . While searching for software that would run on the MS-DOS side of the system, Baker learned of Fido through Madill. The Fido software required changes to

3162-535: The Internet before execution can start on the target's Java virtual machine (JVM). Porting is also the term used when a video game designed to run on one platform, be it an arcade , video game console , or personal computer , is converted to run on a different platform, perhaps with some minor differences. From the beginning of video games through to the 1990s, "ports", at the time often known as "conversions", were often not true ports, but rather reworked versions of

3255-526: The Regional Coordinator, rather than one of the networks that were used to divide the region further. Porting In software engineering , porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program (meant for such execution) was originally designed for (e.g., different CPU , operating system, or third party library ). The term

3348-455: The US into ten regions that they felt would have roughly equal populations. By May, Jennings had early versions of the new software running. These early versions specified the routing manually through a new ROUTE.BBS file that listed network hosts for each node. For instance, an operator might want to forward all mail to St. Louis through a single node, node 10. ROUTE.BBS would then include a list of all

3441-414: The administration of FidoNet nodes and resolve disputes between members. The rules of conduct are summed up into these two deliberately vague principles: Network coordinators are responsible for managing the individual nodes within their area, usually a city or similar sized area. Regional coordinators are responsible for managing the administration of the network coordinators within their region, typically

3534-602: The bounds specified by these standards represents a practical although nontrivial effort. Porting such a program between two standards-compliant platforms (such as POSIX.1 ) can be just a matter of loading the source code and recompiling it on the new platform, but practitioners often find that various minor corrections are required, due to subtle platform differences. Most standards suffer from "gray areas" where differences in interpretation of standards lead to small variations from platform to platform. There also exists an ever-increasing number of tools to facilitate porting, such as

3627-464: The bulletin board software on each end being responsible for ensuring that only the intended recipient could read it. Due to the hobbyist nature of the network, any privacy between the sender and recipient was only the result of politeness from the owners of the FidoNet systems involved in the mail's transfer. It was common, however, for system operators to reserve the right to review the content of mail that passed through their system. Netmail allowed for

3720-608: The calling system would upload its packet, download a return packet if there was one, and disconnect. FIDONET would then unpack the return packet, place the received messages into the local system's database, and move onto the next packet. When there were no remaining packets, FIDONET would exit, and run the FIDO BBS program. In order to lower long-distance charges, the mail exchanges were timed to run late at night, normally 4 AM. This would later be known as national mail hour , and, later still, as Zone Mail Hour . By June 1984, Version 7 of

3813-449: The connection. This initial exchange results in a successful TLS connection (both parties ready to transfer application data with TLS) or an alert message (as specified below). The protocol is used to negotiate the secure attributes of a session. (RFC 5246, p. 37) The WPA2 standard for wireless uses a four-way handshake defined in IEEE 802.11i-2004 . One classic example of handshaking

FidoNet - Misplaced Pages Continue

3906-401: The core group brought up 10C, and most Fido systems had upgraded within a few months. The process went much smoother than anyone imagined, and very few nodes had any problems. Sometime during the evolution of Fido, file attachments were added to the system, allowing a file to be referenced from an email message. During the normal exchange between two instances of FIDONET, any files attached to

3999-489: The costs were attempted, all of which caused friction in the groups. The problems were so bad that Jennings came to refer to the system as the "fight-o-net". As modems reached speeds of 28.8 kbit/s, dial-up Internet became increasingly common. By 1995, the bulletin board market was reeling as users abandoned local BBS systems in favour of a subscription to a local Internet Provider, which allowed access to worldwide internet services, such as HTTP, internet mail and so on, for

4092-438: The data was corrupted en route). Handshaking facilitates connecting relatively heterogeneous systems or equipment over a communication channel without the need for human intervention to set parameters. Establishing a normal TCP connection requires three separate steps: The reason for the client and server not using a default sequence number such as 0 for establishing the connection is to protect against two incarnations of

4185-428: The earliest standards. File attachments followed the normal mail routing through multiple systems and could back up transfers all along the line as the files were copied. Additionally, users could send files to other users and rack up long-distance charges on a host systems. For these reasons, file transfers were normally turned off for most users, and only available to the system operators and tosser/scanners. A solution

4278-466: The early 1990s, combined with the rapid decrease in price of computer systems and storage, made BBSes increasingly popular. By the mid-1990s there were almost 40,000 FidoNet systems in operation, and it was possible to communicate with millions of users around the world. Only UUCPNET came close in terms of breadth or numbers; FidoNet's user base far surpassed other networks like BITNET . The broad availability of low-cost Internet connections starting in

4371-553: The email database for any messages with a number in this field. FIDONET collected all of the messages for a particular node number into a file known as a message packet . After all the packets were generated, one for each node, the FIDONET program would look up the destination node's phone number in NODELIST.BBS, and call the remote system. Provided that FIDONET was running on that system, the two systems would handshake and, if this succeeded,

4464-477: The end of that year. Steady growth continued through the 1980s, but a combination of factors led to rapid growth after 1988. These included faster and less expensive modems and rapidly declining costs of hard drives and computer systems in general. By April 1993, the FidoNet nodelist contained over 20,000 systems. At that time it was estimated that each node had, on average, about 200 active users. Of these 4 million users in total, 2 million users commonly used echomail,

4557-408: The exchange of information that establishes the protocols of a communication link at the start of the communication, before full communication begins. The handshaking process usually takes place in order to establish rules for communication when a computer attempts to communicate with another device. Signals are usually exchanged between two devices to establish a communication link. For example, when

4650-411: The extent to which the original environment (the source platform ) differs from the new environment (the target platform ), the experience of the original authors in knowing which programming language constructs and third party library calls are unlikely to be portable, and the amount of effort invested by the original authors in only using portable constructs (platform specific constructs often provide

4743-509: The file to be copied multiple times. Two such standards became common, "WaZOO" and "Bark", which saw varying support among different mailers. Both worked similarly, with the mailer calling the remote system and sending a new handshake packet to request the files. Although FidoNet was, by far, the best known BBS-based network, it was by no means the only one. From 1988 on, PCBoard systems were able to host similar functionality known as RelayNet , while other popular networks included RBBSNet from

4836-469: The first minute of the call, was normally billed at a higher rate than continuing an existing connection. Therefore, it would be less expensive to deliver all the messages from all the users in San Francisco to all of the users in St. Louis in a single call. Packets were generally small enough to be delivered within a minute or two, so delivering all the messages in a single call could greatly reduce costs by avoiding multiple first-minute charges. Once delivered,

4929-563: The first version of the FidoNet software in June 1984. In early 1985 he wrote a document explaining the operations of the FidoNet, along with a short portion on the history of the system. In this version, FidoNet was developed as a way to exchange mail between the first two Fido BBS systems, Jennings' and Madill's, to "see if it could be done, merely for the fun of it". This was first supported in Fido V7, "sometime in June 84 or so". In early 1984, Ben Baker

5022-452: The games due to the limitations of different systems. For example, the 1982 game The Hobbit , a text adventure augmented with graphic images, has significantly different graphic styles across the range of personal computers that its ports were developed for. However, many 21st century video games are developed using software (often in C++ ) that can output code for one or more consoles as well as for

5115-486: The global list. At a meeting held in Kaplan's living room in St. Louis on 11 April 1985 the various parties hammered out all of the details of the new concept. As part of this meeting, they also added the concept of a region , a purely administrative level that was not part of the addressing scheme. Regional hosts would handle any stragglers in the network maps, remote systems that had no local network hosts. They then divided up

5208-406: The higher levels of performance that computers generally have being underutilized, partially due to console hardware being fixed throughout their run (with games being developed for console specs), while PCs become more powerful as hardware evolves, but also due to ported games sometimes being poorly optimized for PCs, or lazily ported. While broadly similar, architectural differences may exist such as

5301-456: The known systems in that area, with instructions to forward mail to each of those nodes through node 10. This process was later semi-automated by John Warren's NODELIST program. Over time, this information was folded into updated versions of the nodelist format, and the ROUTES file is no longer used. A new version of FIDO and FIDONET, 10C, was released containing all of these features. On 12 June 1985

5394-408: The latter machines' sprites and other sophisticated features made porting from them to Apple "far more difficult, perhaps even impossible". Reviews complained of ports that suffered from "Apple conversionitis", retaining the Apple's "lousy sound and black-white-green-purple graphics"; after Garriott's statement, when Dan Bunten asked "Atari and Commodore people in the audience, are you happy with

5487-432: The message in while on a long-distance telephone connection. Jennings responded by calling into Baker's system that night and uploading a new version of the software consisting of three files: FIDO_DECV6, a new version of the BBS program itself, FIDONET, a new program, and NODELIST.BBS, a text file. The new version of FIDO BBS had a timer that caused it to exit at a specified time, normally at night. As it exited it would run

5580-457: The messages in the packets were delivered after the packet itself had been up or downloaded. It is not clear when this was added, but it was already a feature of the basic system when the 8 February 1985 version of the FidoNet standards document was released, so this was added very early in Fido's history. At a sysop meeting in Dallas, the idea was raised that it would be nice if there was some way for

5673-495: The mid-1990s lessened the need for FidoNet's store-and-forward system, as any system in the world could be reached for equal cost. Direct dialing into local BBS systems rapidly declined. Although FidoNet has shrunk considerably since the late 1990s, it has remained in use even today despite internet connectivity becoming more widespread. There are two major accounts of the development of the FidoNet, differing only in small details. Around Christmas 1983, Tom Jennings started work on

SECTION 60

5766-418: The net/node addressing scheme was also useful for reducing communications costs between continents, where time zone differences on either end of the connection might also come into play. For instance, the best time to forward mail in the US was at night, but that might not be the best time for European hosts to exchange. Efforts towards introducing a continental level to the addressing system started in 1986. At

5859-444: The netmail from all of the systems in their network, then re-package it into single packets destined to each network. They would then call any required network admin sites and deliver the packet to them. That site would then process the mail as normal, although all of the messages in the packet would be guaranteed to be local calls. The network address was placed in an unused field in the Fido message database, which formerly always held

5952-481: The new scheme was that node numbers were now unique only within their network, not globally. This meant the previous 250 node limit was gone, but for a variety of reasons this was initially limited to about 1,200. This change also devolved the maintenance of the nodelists down to the network hosts, who then sent updated lists back to Node 51 to be collected into the master list. The St. Louis group now had to only maintain their own local network, and do basic work to compile

6045-409: The normal netmail scan, but these files were then compressed and attached to a normal netmail message as an attachment. This message was then sent to a special address on the remote system. After receiving netmail as normal, the scanner on the remote system looked for these messages, unpacked them, and put them into the same public forum on the original system. In this fashion, Rush's system implemented

6138-493: The origin system's name and address. After that, each system that the message traveled through added itself to a growing PATH header, as well as a SEENBY header. SEENBY prevented the message from looping around the network in the case of misconfigured routing information. Echomail was not the only system to use the file attachment feature of netmail to implement store-and-forward capabilities. Similar concepts were used by online games and other systems as well. The evolution towards

6231-413: The original netmail system. By the early 1990s, echo mail was carrying over 8 MB of compressed message traffic a day, many times that when uncompressed. Echomail did not necessarily use the same distribution pathways as normal netmail, and the distribution routing was stored in a separate setup file not unlike the original ROUTES.BBS. At the originating site a header line was added to the message indicating

6324-402: The overhead of nodelist maintenance was desirable. In October 1986 the last major change to the FidoNet network was released, adding zones and points . Zones represented major geographical areas roughly corresponding to continents. There were six zones in total, North America, South America, Europe, Oceania, Asia, and Africa. Points represented non-public nodes, which were created privately on

6417-546: The packet would be broken out into separate packets for local systems, and delivered using multiple local free calls. The team settled on the concept of adding a new network number patterned on the idea of area codes . A complete network address would now consist of the network and node number pair, which would be written with a slash between them. All mail travelling between networks would first be sent to their local network host , someone who volunteered to pay for any long-distance charges. That single site would collect up all

6510-445: The passing of commands. A simple handshaking protocol might only involve the receiver sending a message meaning "I received your last message and I am ready for you to send me another one." A more complex handshaking protocol might allow the sender to ask the receiver if it is ready to receive or for the receiver to reply with a negative acknowledgement meaning "I did not receive your last message correctly, please resend it" (e.g., if

6603-404: The ported code generator or interpreter, thus producing the compiler software or directly executing the intermediate code on the interpreter. The machine independent part can be developed and tested on another machine (the host machine ). This greatly reduces design efforts, because the machine independent part needs to be developed only once to create portable intermediate code. An interpreter

6696-448: The record encapsulates a "control" protocol—the handshake messaging protocol (content type 22). This protocol is used to exchange all the information required by both sides for the exchange of the actual application data by TLS. It defines the messages formatting or containing this information and the order of their exchange. These may vary according to the demands of the client and server—i.e., there are several possible procedures to set up

6789-447: The same connection reusing the same sequence number too soon, which means a segment from an earlier incarnation of a connection might interfere with a later incarnation of the connection. The Simple Mail Transfer Protocol (SMTP) is the key Internet standard for email transmission. It includes handshaking to negotiate authentication, encryption and maximum message size. When a Transport Layer Security (SSL or TLS) connection starts,

6882-399: The same cost as accessing a local BBS system. Many BBS sysops became Internet Service Providers. Their Internet gateways also made FidoNet less expensive to implement, because inter-net transfers could be delivered over the Internet as well, at little or no marginal cost. But this seriously diluted the entire purpose of the store-and-forward model, which had been built up specifically to address

6975-425: The same time, it was noted that some power users were interested in using FidoNet protocols as a way of delivering the large quantities of echomail to their local machines where it could be read offline. These users did not want their systems to appear in the nodelist - they did not (necessarily) run a bulletin board system and were not publicly accessible. A mechanism allowing netmail delivery to these systems without

7068-563: The screen creating a flickering effect. The poor performance of the Atari 2600 Pac-Man is cited by some scholars as a cause of the video game crash of 1983 . Many early ports suffered significant gameplay quality issues because computers greatly differed. Richard Garriott stated in 1984 at Origins Game Fair that Origin Systems developed video games for the Apple II first then ported them to Commodore 64 and Atari 8-bit computers , because

7161-407: The separate FIDONET program. NODELIST was the list of Fido BBS systems, which Jennings had already been compiling. The FIDONET program was what later became known as a mailer . The FIDO BBS software was modified to use a previously unused numeric field in the message headers to store a node number for the machine to which the message should be delivered to. When FIDONET ran, it would search through

7254-704: The serial drivers to work properly on the Rainbow. A porting effort started, involving Jennings, Madill and Baker. This caused all involved to rack up considerable long-distance charges as they all called each other during development, or called into each other's BBSes to leave email. During one such call "in May or early June", Baker and Jennings discussed how great it would be if the BBS systems could call each other automatically, exchanging mail and files between them. This would allow them to compose mail on their local machines, and then deliver it quickly, as opposed to calling in and typing

7347-479: The shared public forums, while about 200,000 used the private netmail system. At its peak, FidoNet listed approximately 39,000 systems. Throughout its lifetime, FidoNet was beset with management problems and infighting. Much of this can be traced to the fact that the inter-net delivery cost real money, and the traffic grew more rapidly than decreases caused by improving modem speeds and downward trending long-distance rates. As they increased, various methods of recouping

7440-555: The size of a state, or small country. Zone coordinators are responsible for managing the administration of all of the regions within their zone. The world is divided into six zones, the coordinators of which elect one of themselves to be the International Coordinator of FidoNet. FidoNet was historically designed to use modem-based dial-up access between bulletin board systems, and much of its policy and structure reflected this. The FidoNet system officially referred only to

7533-405: The sysops to post messages that would be shared among the systems. In February 1986 Jeff Rush, one of the group members, introduced a new mailer that extracted messages from public forums that the sysop selected, similar to the way the original mailer handled private messages. The new program was known as a tosser/scanner . The tosser produced a file that was similar (or identical) to the output from

7626-426: The system was being run in production, and nodes were rapidly being added to the network. By August there were almost 30 systems in the nodelist, 50 by September, and over 160 by January 1985. As the network grew, the maintenance of the nodelist became prohibitive, and errors were common. In these cases, people would start receiving phone calls at 4 AM, from a caller that would say nothing and then hang up. In other cases

7719-513: The system would be listed before it was up and running, resulting in long-distance calls that accomplished nothing. In August 1984, Jennings handed off control of the nodelist to the group in St. Louis, mostly Ken Kaplan and Ben Baker. Kaplan had come across Fido as part of finding a BBS solution for his company, which worked with DEC computers and had been given a Rainbow computer and a USRobotics 1200bit/s modem . From then on, joining FidoNet required one to set up their system and use it to deliver

7812-573: The target. According to the designers of the BCPL language, interpreted code (in the BCPL case) is more compact than machine code, typically by a factor of two to one. Interpreted code however runs about ten times slower than compiled code on the same machine. The designers of the Java programming language try to take advantage of the compactness of interpreted code, because a Java program may need to be transmitted over

7905-405: The terms "arcade perfect" or "arcade accurate" were often used to describe how closely the gameplay, graphics, and other assets on the ported version matched the arcade version. Many arcade ports in the early 1980s were far from arcade perfect as home consoles and computers lacked the sophisticated hardware in arcade games, but games could still approximate the gameplay. Notably, Space Invaders on

7998-426: The transfer of Netmail —the individual private messages between people using bulletin boards—including the protocols and standards with which to support it. A netmail message would contain the name of the person sending, the name of the intended recipient, and the respective FidoNet addresses of each. The FidoNet system was responsible for routing the message from one system to the other (details below), with

8091-433: The use of unified memory on a console. Handshake (computing) In computing, a handshake is a signal between two devices or programs, used to, e.g., authenticate, coordinate. An example is the handshaking between a hypervisor and an application in a guest virtual machine . In telecommunications , a handshake is an automated process of negotiation between two participants (example " Alice and Bob ") through

8184-416: The user can telnet to any BBS worldwide as cheaply as ones next door. Also, Usenet and internet mail has been added, along with long file names to many newer versions of BBS software, some being freeware , resulting in increasing use. Nodelists are no longer declining in all cases. FidoNet is governed in a hierarchical structure according to FidoNet policy, with designated coordinators at each level to manage

8277-402: The virtual machine is even simpler than the target CPU. Writing the compiler sources entirely in the programming language the compiler is supposed to translate, makes the following approach, better known as compiler bootstrapping , feasible on the target machine: The difficult part of coding the optimization routines is done using the high-level language instead of the assembly language of

8370-420: Was added to the nodelist. The first new nodelist was published on 21 September 1984. Growth continued to accelerate, and by the spring of 1985, the system was already reaching its limit of 250 nodes. In addition to the limits on the growth of what was clearly a popular system, nodelist maintenance continued to grow more and more time-consuming. It was also realized that Fido systems were generally clustered – of

8463-410: Was offered in the form of file requests . This reversed the flow of information, instead of being driven by the sending systems, these were driven by the calling system. This meant it was the receiver, the user trying to get the file, that paid for the connection. Additionally, requests were directly routed using one-time point-to-point connections instead of the traditional routing, so they did not cause

8556-588: Was planning on starting a BBS for the newly forming computer club at the McDonnell Douglas automotive division in St. Louis . Baker was part of the CP/M special interest group within the club. He intended to use the seminal, CP/M-hosted, CBBS system, and went looking for a machine to run it on. The club's president told Baker that DEC would be giving them a Rainbow 100 computer on indefinite loan, so he made plans to move

8649-402: Was supported by a variety of software that collected up new messages from the local BBSes' public forums (the scanner ), compressed it using ARC or ZIP , attached the resulting archive to a Netmail message, and sent that message to a selected system. On receiving such a message, identified because it was addressed to a particular user , the reverse process was used to extract the messages, and
