No, most likely what you've got there is a Pertec-formatted tape
controller.  Maybe a TC12.  Emulex also made some serial port cards
that have 2 50-pin connectors, though.  Read me the numbers off the
Emulex sticker and we'll see what you really have.

Some Unibus and Q-bus Emulex docs are available from the anon ftp site

sunsite.unc.edu

in the directory

/pub/academic/computer-science/history/pdp-11/hardware

I also have paper copies of most of the Emulex Q-bus and Unibus controller
manuals.
