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)
         Q/B A4.0"

(Etching on card component side)
        "211 00031 Rev. E"

(Another etching on component side)
        "(C) 1987 Made in USA Assy 210-00031"

Physical characteristics - dual width board, 50 pin connector on board
with a single red LED near the connector.

I'd appreciate it if someone could clue me in on the identity of the
card - i'm rather curious as to what it is! :)
