I have several old, functional PCs stored away.
Vic-20 , Commodore64, Commodore 128D, Amiga 2000, Amiga 3000, Ti99-4A, Apple 2E, Radio Shack TRS-80 Pocket Computer, Atari XL. I collect these things.
I have other interesting hardware as well, such as an original IBM 5150 PC case that I intend to modify and install a new system in and use as my main desktop computer.
Just a couple weeks back, I managed to salvage the first videogame I had written for Vic-20 off of a thirty year old 'Datasette' I found in an old box.
