My assumption, actually, is that it's a

adaptor for the projector. The presence of ADB and PS/2
ports would make me guess that it's so you can attach a
mouse (some projectors used it for their config screens,
others let you control the host machine's cursor through
the remote, which would indicate the other direction).
The DE9 is probably for a serial mouse (which I recall
being pretty popular before PS/2 was ubiquitous).
Serial mice normally mated to a DE9M!
(suitable for connecting the projector to serial of host computer
for control of host computer, not for attaching mouse to projector)
Which would bolster the second possibility, that it's meant
for controlling the host rather than the projector.
But, we are opining over something inconsequential.
Pay postage, and YOU CAN HAVE IT!
I appreciate the offer, but I have overflowing cable bins
and even less use for that one than many of the other
esoteric cables I have in the bins.
