A quick Google search nor looking through Emulex's site was I able to find
out what this card is?
The actual number is QD2110202-00 rev L. From the connectors it is either
ESDI or a MFM hard disk controller for Qbus but I am not sure which.

It's a QD21. Here's what Megan's (et al) module list at
<http://world.std.com/~mbg/pdp11-field-guide.txt> says:
: QD21 Q Emulex ESDI disk controller. Emulates MSCP.
: Has LSI-11 boot, LSI-11 & VAX config and
: diagnostic programmes in ROM, NVRAM config
: settings. Q22.
The actual number is QD2110202-00 rev L.
Emulex's "assy numbers" are wierd like that. Sometimes it makes it quite
difficult to identify a board.
While we're at it, would someone here please demystify the format and
meaning of Emulex assy numbers?

The ST412/506 (MFM)card would have pins 2/4/6/8 of the 20-pin connector
at ground potential. On ESDI, only '6' of that group would be at
ground.
