Amstrad CPC ROM Card.
Two ROM sockets can each take either a 16KByte EPROM or a 32KByte E(E)PROM. Using 32KByte parts gives a capacity equivalent to 4 original ROMS.
The DIP switches on the RHS of the board determine which ROM sockets are enabled and how they are mapped into the ROM space. The left most socket can also be used to replace the lower ROM (Firmware) - for example in a CPC464 using a 32KByte device in the left most socket can be used to replace the existing firmware with that from a CPC6128.
Status
Boards built and fully tested. No problems.
