I don't have a ZX80 to sell. (I'd like one too.) I can address part of
the problem. There is a place which has instructions, part lists, ROM
images, schematics, etc. for building a ZX80. Below is the article posted
to alt.comp.hardware.homebuilt last December.

If you are interested in the internal workings of the ZX80 or ZX81 and
would like to build a ZX80 yourself using readilly available
components then please check out the following site:

The later ZX81 is very similar to the ZX80 except a lot of the ICs in
the 80 has been merged into one chip. As a result, you can learn a lot
about the workings of the ZX81 by referring to the ZX80 circuit. I
have several computers from the start of the 80's but have always
liked the Sinclair ZX80 for the following reasons:
1. It was so tacky :)
2. It did not have a single dedicated IC in sight.

It is because of the second reason this page has come into existance.
Here I show you how to build your own piece of history. ALL parts for
the ZX80 are available from most of the larger electronic companies.

I hope it is of interest/use.

BTW. As you will see from my site I am a very keen ZX80er. However, I
don't have one (anymore). If you have one (working, dead or in bits)
then please contact me on as I am sure we
can work something out.

The above site is continually under construction as I will add further
details when I have time. All suggestions will be considered.
