Hi, all! I recently purchased a large batch of old QBus
cards to expand
some of the systems in my collection, and one of the cards in the batch
is rather unknown to me... I know its some kind of disk controller,
guessing MSCP ST-506 but I'm wondering if its SCSI because i'm seeing
some resistor packs on the board that could be terminating resistors,
I suppose... anyways, here's the information:
(Label on top of large 48 pin IC)
"TD Systems Inc.
Lowell, MA - USA
VIK/QDT #2111"
(Label on 28 pin ROM)
"Viking
Q/B A4.0"
It's a Viking QDT, a Q-bus host adapter for SCSI disks and tapes. (That's
what the "DT" in QDT means.)
