I recently acquired an original KIM-1 microcomputer. This is quite an interesting and historically important machine, being one of the first affordable microcomputers.
This particular machine also has an interesting history. I've covered it in a YouTube video, and intend to create some more videos in the series.
For the last couple of weeks I have been entering a and running the programs from The First Book of KIM-1. I've put buildable source code as well as binary download files on my github account.
