I decided to give this a go on real hardware as well, trying to avoid opening and modifying the ZX81. Only modification to my setup, which has been done long time ago - My ZX81 has internal 16K RAM upgrade (WRX compatible) and a composite mod.

I know it looks like chaos, but huuraaa - it's working - my ZX81 thinks it's a ZX Spectrum

and everything needed is connected to the expansion port of the ZX81.

...and yes, there is an EEPROM in there somewhere...
