Retail Cartridges

Only ten ROM cartridge titles were ever released, although others were planned but never completed due to the lack of demand for software in ROM cartridge format. The first cartridges released about September/October 1983 and were the Psion titles Planetoids, Backgammon and Space Raiders. These were followed a couple of months later by Chess, and then the remaining six titles in December 1983. Sinclair Research Ltd did produce another ROM cartridge title which was a System Test Cartridge for use in diagnosing faults was a Spectrum system, but this was only available to service centres. Parker Brothers produced a range of prototype cartridges but these were never released. However, it is possible to construct new custom cartridges for use with the ZX Interface 2.

Custom Cartridge Designs

This section describes a range of methods for creating custom ROM cartridges, and the range of PCBs I have produced to demostrate some of these techniques. It is followed by sections that present new ROM cartridge programs for use with these PCBs. Each program is represented by a thumbnail of the lowest specification PCB that it will run it. All third party ROMs are shown using an alternate PCB thumbnail and will work on the ZXC1, ZXC2, ZXC3 and ZXC4 PCBs. Most of the programs presented can be programmed into the ZXC3 using its built in FLASH programming mechanism, but some are only supported using an EPROM programmer (as noted on each program's page). All programs can be programmed into the ZXC4. All programs have been tested with the various UK released Spectrum models but should also work on modified versions that were released overseas. I have a number of these PCBs available for purchase, and can also supply them ready assembled, cased and pre-programmed (see the web page for each PCB to check availability).
