Description
ZX Spectrum diagnostic ROM
The interface allows you to connect an external ROM. The interface uses a 64K x 8-bit memory organization system, e.g. EEPROM W27C (E) 512 - 4 banks 16KB each, switched with DIP switch, which gives us the opportunity to run 4 different ROMs. After uploading the diagnostic ROMs, it can be used as a simple diagnostic interface for repairs.
The interface will work properly with computers:
ZX Spectrum 48
ZX Spectrum 128
ZX Spectrum +2
Timex 2048
The interface does not work with ZX Spectrum 128 + 2A / B and +3 computers
