Wow, I don't feel so bad now with all the stuff I have (or had) at one point or another.
Currently have a combination of old and new stuff which includes:
Amiga 500 (w/GVP HD+8)
Amiga 1200
Amiga 3000 (working on getting that 4060 board fitted)
Apple IIgs (w/ Zip Chip, hard drive, and rare Apple CD-ROM)
Mac Quadra 630 (overclocked to 40 MHz, OS 8.1, but very badly yellowed)
PowerMac G5 / Dual 2.7GHz
2008 MacBook 15-Inch
2009 Mac Mini
2x PC clones featuring Dual Xeons / Asus PC-DL motherboard
2x PC clones featuring overclocked Core 2 Quads @ 3.5 and watercooled
2x Sega Dreamcasts (one never opened)
Gamecube
Xbox 360
PS3
Wii
Magnavox Odyssey 2 (no clue if that still works, I think I'll need to find out soon!)
Atari Lynx (acting up with corroded game contacts last time I checked)
PSP
At one point or another I also had a:
TI 99/4A (with the MBX joystick and keypad add-on)
Apple IIe (with a whopping 1MB of memory)
PowerMac 9500 (w/800MHz G4 running OS X)
PowerMac G4 Cube (1.7GHz dual processor upgraded)
Super Nintendo (taken by the ex-girlfriend)
Nintendo 64 (also taken by the ex)
Another Gamecube (the ex again)
Original Xbox (current girlfriends brother took that)
Another Amiga 500
Another Amiga 1200
Another Amiga 3000
I regret selling my G4 Cube and original Amiga 1200 at this time. The G4 Cube, although slower compared to the G5 I still have, was definitely a marvel of engineering for the point in time it came out. And the original A1200 was a heck of a lot more stable and decked out than the unit I currently have. I also have a N64 cartridge of "Duke Nuken Zero Hour" that I'll probably never play again. Boo-hoo...
