Yes, it's a desktop system. From what I can make out from the photos, IC

Scroll down to find the images of a desktop unit. The pics look just
like an FX31 that was advertised on ebay.co.uk earlier on this year.
Yes, that's the critter!

Morning folks,
I've been contacted by a teacher who's looking for any information about

My Portable II uses a Miniscribe ST506/412 drive hooked up to a bridge
board that I'm told is IDE at the other side, back to the controller. The
original drive in my machine is toast - I had to pop the lid to free the
spindle. It spins up now, and might cough up some data (for a while), so

If we're rambling about SGIs now, my all time fav. is the Indigo 2 R1000

machines I've ever encountered.

Yes, from Acorn: ARM, 32016, 6502, 65C102, Z80, 80186 and 80286.
Torch did a couple of different Z80 boards too, and a couple of different

Nice collection. I'd forgotten about the 32016! What software ran on these

OS-wise the 32016 ran something called Panos, with Pandora as the firmware
