Description

The ZXC1 combines the techniques employed in the standard, switched bank paging and timed bank paging ROM cartridge configurations. It supports 8K (27C64), 16K (27C128), 32K (27C256) and 64K (27C512) EPROMs, and provides space to mount three LEDs to indicate the state of each of the paging circuits. The PCB is shown below.

The switched bank paging configuration allows up to 2 switches to select any one of 4 banks of 16K. The timed bank paging configuration allows up to 4 banks of 16K to be cycled through in sequence, thereby allowing 48K games to be stored within the cartridge.

Two batches of the PCB were produced, the first had a silver coloured edge connector whereas the second had a gold edge connector for improved electrical contact. The electrical circuit remained identical.
