Retro Computers Wiki

Welcome to the Retro Computers Wiki (Started Apr 2014)

This Wiki is dedicated to computers from the 1980's and early 90's and my experience of programming them.  The ones currently illustrated are from my collection but if you have others please feel free to add a page and a picture and add your own programming or other experiences of these old beasts. If you do start another computer page please put your signature on it so I know it's not mine!

As this Wiki is not primarily about the hardware, only the basic specification of the machines are given with links to sites where you can get much more detail. However, If I have anything interesting to write, I will.

PS - Some of the pictures are a bit crabby as my photographic skills are sub-optimal; but I will replace the worst ones eventually!
