I wanna know. Name what you have spec-wise, and what OS you are running. I know there has to be quite a few here.
I have -
iMac Snow, running OS X 10.4
256MB ram <---- Soon to be a gig
19" LCD external monitor hooked up, iMac doesn't fit on this desk
Power Macintosh 7100/80AV, running OS 8.6
PowerPC 601 80Mhz
15" Apple Display
iMac Bondi, running 9.2.2
Macintosh Classic II, running 7.6.1
All of them work, the Snow is my everyday one, all the others are put away.
