RO(A)M Interface for ZX81
16KB RAM + 4 banks of 8KB ROM interface for Sinclair ZX81. ROM banks are selectable via DIP switches and they are mapped in between 8K to 16K of ZX81 memory map. ROM banks are for storing software issued on cartridges for ZX81 and need to pre-programmed prior to soldering the ROM chip to the board.
The interface is the outcome of my own works and tested as far as practically possible.
No Warranty of the Project. The Issuer makes no express or implied warranty of any kind whatsoever with respect to the published files.
