Sadly the RAM and ULA are both dead. RAM not an issue as I will upgrade it to 16K but the ULA is. I have run out of spares. Hopefully Andy is making another batch soon!

Re: Lardo buys another zeddy
And here we have the limited ‘Hoth’ edition ZX81 released in honour of The Empire Strikes back. How on earth did they do this?
It also looks like someone used a scourer to remove a label at some point.

Re: Lardo buys another zeddy
Been a while so here is an early issue one that came with a ZX80 black PSU. It kind of works...
The ULA is 8106 but the Z80 is 8805. I guess it was repaired at some point.

Re: Lardo buys another zeddy
Another issue one. It had a bugged ROM. And well attached RAM pack.
Really well attached...

Re: Lardo buys another zeddy
All working but clearly repaired at some point! A turned pin green socket. Nice.
Edit - the ULA died while testing.

Re: Lardo buys another zeddy
Another one. 
This is an early (8106) self built one with a ZX80 16K RAM pack. It has the bugged ROM.
All working so far! Only tested the RAM briefly by doing DIM A(3000) and it returning 0/0.
The last three I have had all had dodgy ULAs. Heres hoping for better luck with this one.

Re: Lardo buys another zeddy
I must admit I bought this mainly for the case as I have one to sell that it is very poor condition and this one is much better.
But I was also curious about the RAM!

Re: Lardo buys another zeddy
Not quite a zeddy but still a lovely bit of working Sinclair goodness.

That’s darn reasonable for a working issue one, well done
