Thanks for the welcome, lassie.
For consoles I have the Atari 2600, Atari 7800, NES, SNES, N64, Gamecube, Wii, Master System, Genesis, PS1, and PS2. Plus a few variants and duplicates.
For computers I have the C64 (and 64C), A1000 (just got for free a couple of days ago!), A1200, and a TI-99 with no software. Plus a few random, more "modern" ('94 - '99) machines that I've picked up at yard sales and what-not for storage and experimenting with Linux.
Then we have some of the same machines
