Assorted free comms gear etc. (Milton Keynes, UK)

Hi, Somebody dropped off the following items (operational condition unknown) to the Bletchley Park computer museum the other week which we can't really make any use of: Two Racal Milgo Omnimux 82 advanced statistical multiplexors An ACT SDM-T (seems to convert several analogue phone lines to digital) An X-TEC Protocol Converter A Wellfleet Access Node Communications Server Large industrial rack system with 5" VGA display, Colorado 1440 tape drive, 3.5" floppy, PSU, and a huge backplane containing 4 PCI slots and 15 ISA slots. We actually have two units, but may be keeping the screen - maybe the backplane and chassis is still useful to someone though. I believe there's the PC-on-a-card board kicking around the office from one of the racks, the other one arrived with a bare backplane though. They're free to a good home; comms gear isn't really my thing so I just grabbed what was on the front labels - if any of the above sounds like it could be useful to anyone I can always get more details as to exact model numbers, what interfaces they have etc. cheers Jules
