Faulty ZX81

Post by 1024MAK »

Hello, if anyone has a faulty ZX81, I'm after one. I'm not worried about if the ULA is present or faulty. As I'm more interested in the PCB and the case. Again, I'm not bothered about the state of the keyboard membrane.

If you have one, please either PM me or post a reply here giving details ;)

There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb :!:
Looking forward to summer later in the year.

Mark,

I have a spare one, if you are only looking for the main unit?

It seems to be working OK apart from keys 1 - 5. Issue 3 mainboard.

Let me know if you are interested.
