Unbuilt ZX81 up for adoption

Post by Lardo Boffin » Thu May 17, 2018 10:31 pm

A while back I bought an unbuilt ZX81 kit with the intention of building it. I have not built it and cannot bring myself to do so. :oops:

I have umm’d and arrr’d and eventually gone down the route of building my own from new components (with limited success but as soon as I get a working 6.5 MHz resonator I should be sorted). Anyway I have decided I can’t build this but someone else should.

So it is up for sale at what I paid for it plus about a fiver (got to make a little profit) and p&p (within the UK - elsewhere will be more). This comes to £130. Obviously I can make no guarantees that it will work!

Assuming anyone is interested (it is a lot cheaper than eBay tends to be but is still a chunk of cash) then please pm me.

Only caveat of sale - you must build it! I would also be sad if it ended up on eBay. I could sell it for more on there myself.

This has gone to Andy. I know I said I wanted it building and andy isn’t going to but as he is working on a repacement ULA I figured I could overlook this fact. :D

I would like that as well for debugging purposes on my broken ZX81.
