Acorn Aatom

By pcollins.

I still have mine in the loft somewhere, built by my own fair hand in 1980!

I recall having to solder 113(!) chip sockets and having to align all the keyboard pins to solder it to the motehrboard.

I upgraded mine to a whole 10K of RAM, which I think cost me about £35!

It worked first time, but I had random characters on the display. I called Acorn and asked for technical support, only to be told, "He's on Holiday" I finally found a bent pin on the video controller ship and it worked fine, and continued to do so.

Might even work now if I can find it...
