I'm actually hoping I can pick up a USB-ADB adapter at a non-ridiculous price. I want to keep using my Extended KBII, Logitech trackball and Wacom graphics tablet. For now, I'm borrowing my housemate's iMac keyboard till I find either a USB set or the USB-PS/2 converters I know I have .... somewhere.
Believe it or not, I don't seem to have any PS/2 keyboards about the place. I know there's a box of mice ... somewhere.
Tonight it's up and running with the dual 533 G4s. I had to cut the connector off the CPU shroud fan, solder the leads to a couple of pins (made, literally, from pins) heatshrink them into a neat little bundle and shove them into yet another unused floppy connector. And the case fan has quietened down a lot - must have been cranky from lack of use.
That was after the hour I spent making up a disk power double adapter from a dead PS - then realising it didn't have a female connector.
My *ahem* backup 10.3 CDs aren't booting; 10.2 is but there are "problems installing the software; please try again". I suspect a flaky CD drive. I tried my hard-rubbish-day Pioneer DVDR, but that doesn't appear to be bootable. Next attempt will be a slower CD drive, because that seemed to help last time on the beige.
Dunno if it's relevant or not but the drive I'm installing to is 160GB. I've formatted the space that can be seen (132GB) into four partitions.
I do have a PCI ATA controller and a SCSI card, but I don't know if they are supported under OS X or not, so I haven't tried to install them yet.
Right now DiskWarrior is having a go at repairing the 10.2 HD out of my beige.
