So I did end up picking up the PC 10-III from YetiSeti...
She's fully loaded as far as the PC 10 series goes - 20MB WD90328X 8-bit IDE HDD, 640K RAM. She's a runner, but not without its issues. The old WD spins up fine but the head stepper goes crazy and the machine can't boot from the drive. The floppy drive had a business card jammed in it (!!!). And after hours of playing trying to get the WD going, it's stopped recognizing the last 128K of RAM, so it's now a 512K machine I guess
I was yarning to a bloke from Datalab and he did claim he could resurrect the WD without too much dilemma... might take him up on that offer.
Just the local Commodore hobo and middle-aged PC hoarder.
eisa on Trademe. A lasting reminder of a Compaq fetish when I was younger.
