I believe Bun now has 55... I have 19
Well, I was given an iMac G4 today...the last generation 1.25ghz 17" with 1gb of RAM(from the factory). It was the whole Kit'n kaboodle-keyboard, Magic Mouse, white power cord, white pro speakers, the restore disks, and a set of factory Panther disks. I'm excited about that one, although I need to track down one of the iMac G4s that can boot OS 9.
That puts me up to 51 PPC Macs, 5 Intel Macs(plus the iMac on the way), and 2 68Ks. That puts me at 58, or 59 if you count the Intel iMac that I don't have yet.
The only non working computer I'm including in that list is the Rev. A iMac G3. I also have to juggle PSUs to get all the MDDs working, but none the less they will all boot and run with a working PSU.
