Alright, I had a chance today to test the other machines. The 6100 has a 250mhz G3 upgrade in the slot, but I dug out the DOS compatibility card and cable I had kicking around, and plugged that in instead. It also has a 2.5gb HD, and 72mb of RAM. the CD-ROM does not appear to be working, or else I would load the restore CD.

The 6500 has a 6gb HD, 96mb of RAM, a 500mhz G3 sonnet accelerator, though nothing on the outside said so.

Both machines are running Mac OS 9.1.

Still working on the DA G4. I will attempt to safely dissect the power supply, see what died. If anyone has any thoughts, let me know please.
