MountainGate RDR

I recently acquired a MountainGate RDR storage system of some kind. I don't
know much about it or how it would be used, but the price was right...
Anyway, I was wondering if anyone knew anything about this sytem.

What I have are 3 large rackmount cases, Units 0, 1, and 2, each with an ISA
backplane and 8x Quantum Grand Prix 4.3GB drives.
Unit 0 is the controller, with a 486 SBC, 420MB boot drive, parallel/CGA?
card, and 10baseT ethernet. It also has a pair of "Acces I/O Products" model
LT2-AT cards, with 100-pin connectors on the back panel. It then has 4x RAID
controller cards (I think, they are entirely unlabeled) -- the most
prominent/relevant chips are 2x Western Digital WD33C93 and a TI TMS320C25.
Finally, there is some sort of master controller card that sasys
MountainGate on it, with a DB-37 connector on the back panel. The 5
controller cards are connected with a 50 pin ribbon cable bus, and the 4
drive controllers have a pair of 10 pin ribbon cables bussing them together,
one of which goes to a pair of DB9s on the back panel.

Unit 1 and Unit 2 are similarly configured, but with only the 4 drive
controllers and the master controller, and 1 LT2-AT each.

I have tried to power the whole system up, but the only CGA screen I have is
really flaky, so I can tell that _something's_ going on on the screen, but I
can't read it. Hopefully I'll be able to track down an ISA VGA video card
soon; I had one but loaned it to a friend.

If anyone knows anything about this system, please let me know.

Thanks a lot,

Rob Lion
