Welcome to Rob's 1970's and 1980's Retro Computing Archive.

Please visit the main landing page which has a short overview of each repository and why it may be of interest to you.

During the late 1970's and 1980's I was a hard-core, low-level, prolific software and hardware developer, a "builder of everything". This GitHub site will strive, amoung other goals, to bring some of those projects back to life in a documented and open source manner. Fortunately I had documented, archived and stored away most of those projects at the time for future historical recollection.

Generally speaking, the documentation will primarily be of interest to Z-80 and CP/M-80 people, along with some other projects relating to digital music + MIDI synthesis machines and peripheral hardware pinned to the 1980s. A focus will also be made to document some machines for future historical reference.

You can reach me at RetroComputingArchive@gmail.com. I do not have a YouTube channel nor a dedicated Web site for my retro computing work.
