Retro Computing!

A big part of my early life was working on 8-bit and 16-bit computers in the late 70s and 80s, and as I got older I ended up working on more and more plain vanilla x86 type computers.  Even though I have to work on newer computers sometimes, I keep history alive with my collection of retro computers, most of which work even today.  (Note:  I am creating and editing this article on my retro-fitted TRS-80 Model 4 right now!)

This section of the site is dedicated to those with a similar interest in historically significant computers of the past.   I hope you find something of interest and share your comments and thoughts, would love to see and hear about other retro enthusiasts collections, interests and past computers.
