A 5400 uses a BA213 chassis. The lower portion is a 12 slot Qbus backplane.
The upper section has room to mount a tape drive, and up to three RFxx
series drives. The BA213 can be rack mounted, but mostly found in a stand
alone case measuring around 14x20x27. The case has wheels which, given
the weight of the thing, is nice.

It uses a two board KN210 processor set, slot 1 being the I/O module and
slot 2 being the CPU module. It will take up to four MS650 16Mb memory
cards. The processor runs at 20Mhz. It has an MMJ console connector
and both BNC and AUI Ethernet connectors. It will run Ultrix 3.1B or

The RA90 drives are 1.2Gb.

My point is that someone needs to haul this off. I have already got two
of them, or might think about getting it myself. Actually too far away
and the wrong time of the year. I had a dealer in IL offer me $150 for
one, but I decided it was worth more just to play with.

If someone gets this, I have the 5400 hardware manual and will answer what
questions I can. I also have a manual on the RA90/RA92 and the SA600/SA800
Storage Array (that I suspect the drives are mounted in) that I don't
