ROM Cartridge - History

History

A predecessor to the ROM cartridge was found on the 1972 Magnavox home video game console, which used a removable circuit board to reconfigure the game's internal elements; the system had no microprocessor, so there was no firmware to alter.

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.

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).

From the late 1970s to mid-1990s, the majority of home video game systems were cartridge-based. The first system to make use of ROM cartridges was the Fairchild Channel F. As compact disc technology came to be used widely for data storage, most hardware companies moved from cartridges to CD-based game systems. Nintendo remained the lone hold-out, using cartridges for their Nintendo 64 system; the company did not transition to optical media until 2001's GameCube.
