  I was wondering if anyone has a Sinclair ZX80 that
they would like to sell.
 I bought the kit and built one when they first came out. It was my first
 home computer! A few years later somebody stole it from our house after my
 Wife and I had seperated. Why they would steal that I don't know! I have a
 ZX81 but it's just not the same. Of course, it won't be the same not having
 the one I built myself but I'd still like to have one for my collection.
  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:

www.babytalk.demon.co.uk/zx80/zx80.html

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 grant(a)babytalk.demon.co.uk 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.

Grant.
