FYI, I've thrown up a couple of (cell phone) photos of the SC44 boards here:

I'll have the machine home in a few days and I'll be able to take better
pictures then...

Hi all --
I just added a PDP-11/44 to my collection and it appears to have some
manner of cache upgrade; it's made by Digital Data Systems (DDS) and
consists of two cards, one hex-height labeled "SC44 SETASI" (in the
place of the normal 11/44 cache board) and a second quad-height
labeled "1051" at the end of the first backplane. The two are
connected via a ribbon cable.
I know DDS made some seriously nice upgrades for the 11/70 but I can't
find anything on this board set at all. I'm assuming it's just a
souped-up cache but it'd be nice to know more (and docs would be
excellent of course).
Thanks,
Josh
