Mystery LSI-11 board

[tom ponsford]

I got a LSI-11 (11/03) the other day that is pretty much intact, but 
will need some work.
Included with the chassis, backplane and power-supply, were the 
following cards:

LSI-11 CPU M7264 <----------><Quad>
M7940 <dual>             |    DSD  1140-AA floppy ctl <dual>

<------------------<Quad> Mystery/Terminator??---->

Bottom

I do believe the mystery card at the bottom is in fact a 
terminator/bootstrap?? (TEV11/REV11)
But there are no numbers on the handles or on the board.
The plastic handles are grey and are DEC branded. The board has a 40 pin 
connector.
Having never seen a TEV11 or aa REV11 and finding little by googling, 
I'm wonder if anybody out there
can enlighten me!!

I took a picture and excuse me for the size, but I wanted to include as 
much detail as possible!

I also believe the DSD board is a floppy controller.However what looks 
like the model # on the side of the board:
A/1140-6A a small ehite label on the 28 pin eeprom N82S 100I 7851. The 
controller has a fifty pin connector.
Does this look familiar to anybody

Thanks in advance for any help!!
