This page presents details on the range of original retail ROM cartridges, along with my custom ROM cartridge board designs (ZXC1, ZXC2, ZXC3 and ZXC4) and new ROM programs that can be run using them. Each new ROM is represented by a thumbnail of the lowest specification custom board that it will run on. Most of the ROMs presented can be programmed into the ZXC3 and ZXC4 using its built-in FLASH programming mechanism, although some are only supported on the ZXC3 when fitted with an EPROM.

Click on the thumbnail images to see more detail about the corresponding ROM cartridge program.



Retail ROM Cartridges

This section describes the ten retail ROM cartridge titles released by Sinclair. The first titles were released around September/October 1983 and were the Psion games Planetoids, Backgammon and Space Raiders. These were followed a couple of months later by Chess, and then the remaining six titles in December 1983.
