There was a contest thread here way back which I am sure is still here where we all posted pics of our working old systems. I won the contest it was said. I have the following working systems:
Vic-20, C64, C128, Atari 400, 800, 800XL, 130XE and more Ataris, An Atari ST, Amiga, and the very first made in boca rattan Florida IBM 5151 with original monitor and keyboard.
In the end users here back then tore into me for owning so many old systems (it's a hobby of mine) so I backed away and never posted about it again. Hope the same does not happen this time.
