I got a ZX81 yesterday that I was going to refurbish and sell on but the seller had said it was a very early one he built himself so I tried PRINT SQR 0.25 and got this.
Its a bit battered and I have not even wiped it down yet but here it is.
I’m not about to refubish a piece of history so thought I would check to see if anyone on here wanted to adopt it? I already have one.
It cost me £30.95 and includes the PSU (not tested yet) and aerial lead, also not yet tested.
Am happy to pass it on for £30.95 plus p&p if anyone wants it?
The standard output was very dark so used my Chroma once I was sure it worked.
Will add some photos once it is clean.
I will also take photos of the inside if I can do so without damaging the keyboard as this also works.
PM me if interested. All I ask is that it doesn’t end up on eBay.

It has a First Edition manual, that is well used... One page has been sellotaped and there are a few ‘contemporary markings’ and a few finger prints here and there but it is fine as a ‘working’ copy.
