Nice! I would say I have too many to list at this point, but I can try...
Consoles: Atari Lynx(2) and Atari Jaguar. XEGS (guess I can put that there)
Computers: Three above, and TT030 4/16, MegaSTe 4, another 130XE, 800XL, 600XL, 800 and an A4000(060@50).
Ha, for my classic ones, not sure I want to shame myself in saying how many computers besides that I have. I plan on taking one of the 130XEs and putting in the Stereo Pokey, VBXE, and Ultra1mb. Maybe eventually I'll add the Rapidus.
Edit: it's kind of a shame the cartridge port of the XE didn't go where the joystick ports are, it'd really have looked like a baby ST.
Atari 8Bits: 800xl, 600xl, XEGS, 800, 130xe, 130xe (VBXE, U1MB, Stereo POKEY)
Atari STs: 1040STf (broken shifter), 1040STe, Mega STe, TT030, Falcon (CT60e, SuperVidel)
