Thanks for looking at our listing for this Sinclair ZX81 computer, Issue 3 Board

In great condition for its year.

You’ll notice that there’s a bunch of wires around the ROM – this is a factory mod because they’ve fitted an EPROM in the factory instead of a mask programmable ROM. It’s rare, but not super rare!

In good working condition. 

Quite A Nice Tidy Machine.
