The PC-6001 MK2 has 64 KB memory, 16 KB video RAM, a 5 + 1 ⁄ 4 -inch 2D floppy drive interface, Kanji character generator, RGB monitor out, speech synthesizer unit and a typewriter keyboard. It supports following screen modes: 40x20 characters, 80x80 pixel graphics with 15 colors, 160x200 graphics with 15 colors, and 320x200 graphics with 4 colors. Cartridge-based game A ROM cartridge , usually referred to in context simply as

116-454: A game cartridge . ROM cartridges were popularized by early home computers which featured a special bus port for the insertion of cartridges containing software in ROM . In most cases the designs were fairly crude, with the entire address and data buses exposed by the port and attached via an edge connector ; the cartridge was memory mapped directly into the system's address space such that

145-475: A "games" module. Modules were not user-programmable. The Hewlett-Packard HP-41C had expansion slots which could hold ROM memory as well as I/O expansion ports. Computers using cartridges in addition to magnetic media are the VIC-20 and Commodore 64 , MSX , Atari 8-bit computers , TI-99/4A (where they were called Solid State Command Modules and were not directly mapped to the system bus) and IBM PCjr (where

174-436: A cartridge is less than that of an optical disc like a DVD-ROM or CD-ROM . Techniques such as bank switching were employed to be able to use cartridges with a capacity higher than the amount of memory directly addressable by the processor. As video games became more complex (and the size of their code grew), software manufacturers began sacrificing the quick load times of ROM cartridges in favor of greater storage capacity and

203-426: A cassette tape interface, 2 x joystick port, a parallel printer connector, an RF modulator output and a composite video output. The ROM cartridge allowed the user to easily use software such as video games. It supports four screen modes; 32x16 characters with 4 colors, 64x48 pixel graphics with 9 colors, 128x192 graphics with 4 colors, and 256x192 graphics with white and green colors. The Japanese version uses

232-445: A custom " J-Cart " cartridge design by Codemasters which incorporated two additional gamepad ports. This allowed players to have up to four gamepads connected to the console without the need for an additional multi-controller adapter . Storing software on ROM cartridges has a number of advantages over other methods of storage like floppy disks and optical media . As the ROM cartridge

261-466: A form of flash memory technology similar to that of SD cards with larger storage space. As of 2024 , Nintendo is the only major company to exclusively use cartridges for their consoles and handhelds, as others such as Sony and Microsoft continue to use optical disc -based media for their consoles. In 1976 , 310,000 home video game cartridges were sold in the United States. Between 1983 and 2013,

290-681: A manufacturer of consumer electronics. They started manufacturing the PC-8001 and its peripherals which were developed by the Electronic Devices Group of Nippon Electric. It was successful and grew the personal computer market in Japan. They started developing a low-cost home computer, and it became the PC-6001 . At the same time, the Electronic Devices Group developed the PC-8801 for home and business, and

319-410: A plastic "box" open on one side, with pins on one or both sides of the longer edges, sprung to push into the middle of the open center. Connectors are often keyed to ensure the correct polarity , and may contain bumps or notches both for polarity and to ensure that the wrong type of device is not inserted. The socket's width is chosen to fit to the thickness of the connecting PCB. The opposite side of

348-689: A total of 2,910.72 million software cartridges had been sold for Nintendo consoles . ROM cartridges can not only carry software, but additional hardware expansions as well. Examples include various cartridge-based chips on the Super NES , the SVP chip in the Sega Genesis version of Virtua Racing , and a chess module in the Magnavox Odyssey² . Micro Machines 2 on the Genesis/Mega Drive used

377-694: Is memory mapped into the system's normal address space, software stored in the ROM can be read like normal memory; since the system does not have to transfer data from slower media, it allows for nearly instant load time and code execution. Software run directly from ROM typically uses less RAM, leaving memory free for other processes. While the standard size of optical media dictates a minimum size for devices which can read discs, ROM cartridges can be manufactured in different sizes, allowing for smaller devices like handheld game systems . ROM cartridges can be damaged, but they are generally more robust and resistant to damage than optical media; accumulation of dirt and dust on

406-583: Is the portion of a printed circuit board (PCB) consisting of traces leading to the edge of the board that are intended to plug into a matching socket . The edge connector is a money-saving device because it only requires a single discrete female connector (the male connector is formed out of the edge of the PCB), and they also tend to be fairly robust and durable. They are commonly used in computers for expansion slots for peripheral cards, such as PCI , PCI Express , and AGP cards. Edge connector sockets consist of

435-436: The processor being mounted on a card with an edge connector, instead of directly to the motherboard as before and since. IBM PCs used edge connector sockets attached to ribbon cables to connect 5.25" floppy disk drives . 3.5" drives use a pin connector instead. Video game cartridges typically take the form of a PCB with an edge connector: the socket is located within the console itself. The Nintendo Entertainment System

464-555: The 1980s, before Yamaha's Music Cartridge was introduced. Models that used these cartridges were in the Casiotone line of portable electronic keyboards. Amstrad Atari, Inc. Bandai Blaze Entertainment Coleco Fairchild Camera and Instrument Fisher-Price IBM Interton LeapFrog Magnavox / Philips Mattel Milton Bradley NEC Nikko Europe Nintendo Sega SNK Edge connector An edge connector

493-564: The 1980s, such as the DX1 , DX5 and DX7 and their PSR keyboard lineup in the mid-1990s, namely the PSR-320, PSR-420, PSR-520, PSR-620, PSR-330, PSR-530 and the PSR-6000 . These keyboards use specialized cards known as Music Cartridges , a ROM cartridge simply containing MIDI data to be played on the keyboard as MIDI sequence or song data. Casio has also used similar cartridges known as ROM Pack in

522-552: The CPU could execute the program in place without having to first copy it into expensive RAM. The Texas Instruments TI-59 family of programmable scientific calculators used interchangeable ROM cartridges that could be installed in a slot at the back of the calculator. The calculator came with a module that provides several standard mathematical functions including the solution of simultaneous equations. Other modules were specialized for financial calculations, or other subject areas, and even

551-691: The Information Processing Group dealt with the 16-bit personal computer line. NEC Home Electronics discontinued development of the PC-6000 series, the PC-6600 series, and the PC-8000 series. These lines were merged to the PC-8800 series. The PC-6001 has the μPD780 processor (NEC clone of Zilog Z80 ), 16 KB RAM (up to 32 KB), General Instrument AY-3-8910 3-voice sound generator, a ROM Cartridge connector,

580-452: The Information Processing Group developed the PC-9801 for business market. In 1983, New Nippon Electric changed its name to NEC Home Electronics. At that time, NEC group had four personal computer lines come out from different divisions. To avoid conflict, they decided to consolidate personal computer business into two divisions; NEC Home Electronics dealt with the 8-bit home computer line, and

609-421: The cartridge contacts can cause problems, but cleaning the contacts with an isopropyl alcohol solution typically resolves the problems without risk of corrosion. ROM cartridges typically have less capacity than other media. The PCjr-compatible version of Lotus 1-2-3 comes on two cartridges and a floppy disk. ROM cartridges are typically more expensive to manufacture than discs, and storage space available on

638-529: The cartridge was mapped into BIOS space). Some arcade system boards , such as Capcom 's CP System and SNK 's Neo Geo , also used ROM cartridges. Cassettes and floppy disks cost less than ROM cartridges and some memory cards were sold as an inexpensive alternative to ROM cartridges. A precursor to modern game cartridges of second generation video consoles was introduced with the first generation video game console Magnavox Odyssey in 1972, using jumper cards to turn on and off certain electronics inside

667-688: The console. A modern take on game cartridges was invented by Wallace Kirschner, Lawrence Haskel and Jerry Lawson of Alpex Computer Corporation, first unveiled as part of the Fairchild Channel F home console in 1976. The cartridge approach gained more popularity with the Atari 2600 released the following year. From the late 1970s to mid-1990s, the majority of home video game systems were cartridge-based. As compact disc technology came to be widely used for data storage, most hardware companies moved from cartridges to CD-based game systems. Nintendo remained

696-550: The lone hold-out, using cartridges for their Nintendo 64 system; the company did not transition to optical media until the release of the GameCube in 2001. Cartridges were also used for their handheld consoles, which are known as Game Cards in the DS/3DS line of handhelds. These cartridges are much smaller and thinner than previous cartridges, and use the more modern flash memory for game data rather than built-in ROM chips on PCBs for

725-556: The lower cost of optical media. Another source of pressure in this direction was that optical media could be manufactured in much smaller batches than cartridges; releasing a cartridge video game on the other hand inevitably includes the risk of producing thousands of unsold cartridges. Besides their prominent usage on video game consoles, ROM cartridges have also been used on a small number of electronic musical instruments, particularly electronic keyboards . Yamaha has made several models with such features, with their DX synthesizer in

754-549: The same purpose. The release of the Nintendo Switch in 2017 marked the company's shift away from their own proprietary optical disc -based media after last using them in the Wii U in favor of small cartridge-based media. These cartridges are known as Game Cards like previous Nintendo handhelds, and are much smaller and thinner than previous cartridges for consoles as well as Nintendo's own Game Cards for their DS/3DS handhelds. It uses

783-474: The socket is often an insulation-piercing connector which is clamped onto a ribbon cable . Alternatively, the other side may be soldered to a motherboard or daughtercard . Edge connectors are commonly used in personal computers for connecting expansion cards and computer memory to the system bus . Example expansion peripheral technologies which use edge connectors include PCI , PCI Express , and AGP . Slot 1 and Slot A also used edge connectors;

812-436: The time around their release, ROM cartridges provided security against unauthorised copying of software. However, the manufacturing of ROM cartridges was more expensive than floppy disks, and the storage capacity was smaller. ROM cartridges and slots were also used for various hardware accessories and enhancements. The widespread usage of the ROM cartridge in video gaming applications has led it to be often colloquially called

841-555: Was unusual in that it was designed to use a zero insertion force edge connector: instead of the user forcing the cartridge into the socket directly, the cartridge was first placed in a bay and then mechanically lowered into position. Starting with the Amiga 1000 in 1985, various Amiga models used the 86-pin Zorro I edge connector, which was later reshaped into the internal 100-pin Zorro II slot on
