Don't miss our exclusive livestream with a true PC pioneer this Sunday, June 14 at 1PM on VCF's YouTube Channel: https://youtube.com/live/Js6R3OIxi

I found the box sitting on a shelf. I actually bought this new in 1976 and programmed it for a while. It was my first microcomputer.

I recall putting it away when the power supply failed so I don't know if it will still power up. Is there a safe way to test it, and what is a Rev F KIM-1 with all manuals in the original box worth these days, working or not?
