 Notable computers using cartridges in addition to magnetic media were the Commodore VIC-20 and 64, MSX standard, the Atari 8-bit family (400/800/XL/XE), the Texas Instruments TI-99/4A (where they were called "Solid State Command Modules" and were not directly mapped to the system bus) and the IBM PCjr (where 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.The modern take on game cartridges was invented by Jerry Lawson as part of the Fairchild Channel F home console in 1976.
