id this SMS card?

[Joe R.]

  Can anyone id this card?
<http://www.classiccmp.org/hp/PDP-8%20cards/SMS-what.jpg>  I can't find
anything that looks like a model number on it and it doesn't match the
drawings of the three SMS cards on Bitsavers. The most noticable difference
is that the other cards have lots of jumpers all over them and this one
only has a few (7) near the edge connector. The package that it was in only
says "Q-bus SMS Disk IO Bd". The markings on it are Prog Assy 1011939-0002G
(the G may be a 6), Assy No SMS 0003773-0001C, Fab 0003772-0001/c2, AW
0003771/B. Sorry for the crummy picture.
