I only ever ran two of the buggers, T800s, and they were fantastic for
both integer and floating point.

Hi Toby, yeh it's a system I've had for many years and 2 house moves. I
do sometimes find enough time to power it up and start poking about. It
was originally a data mining system built by Whitecross. Organised as 6
T425s per card, each with 16MB ECC RAM. There are 19 cards per sub rack,
and fibre interconnects between each sub-rack. I have 3 "compute" racks,
some storage racks & 2 system controllers (it was originally built as 2
identical systems for redundancy) and 3 48V PSUs - each card has voltage
regulators for the 5V supply. Sadly I couldn't take the original
cabinets so it's housed in a standard open 19" rack now. I'm also very
lucky (Whitecross got in touch when they heard I rescued their largest
system!) to have a pair of specially configured Sun workstations with
custom sbus/fibre adapters (connected via a TTM50 SCSI interface) and
software to run diagnostics on the hardware. Here's some old pics and
documents:

Picked up at a scappers for ?1.20 - they had no clue what it was ;)
Cheers!
