I have four Qbus cards that I am interested in finding
out what they are.
One is a Micro Technology QTS25. It has a 50 pin header. I was wondering if
it was a SCSI card?
It's a tape only SCSI card.
The rest of this is straight out of the field guide that Megan has.

The second is an Emulex QD331040100 Rev. J. This has a
60 pin header and two
26 pin headers. I was wondering if this was a SMD drive controller?
QD33 Q Emulex SMD controller for up to two SMD disks.
Supports SMD-0 and SMD-E, with data rates up to
24MHz for SMD-E. MSCP emulation. DMA (uses
adaptive techniques and block mode, supports
scatter-write and gather-read on the uVAX-I).
The third is a Dilog DQ696-20.vThis has a 34 pin
header and two 20 pin
header. My guess is that it is a MFM or ESDI hard drive controller.
DQ696 Q Dilog 2 x ESDI disk controller. Emulates MSCP.
(supports Fujitsu 2333)
In the same group of cards is a DEC M7546 which I
believe is a TK50 tape
drive controller. Why is it called a Maya Controller?
