I got a bunch of Q-Bus and Unibus boards today, most of which are DEC, and
most of which I was able to identify. One really caught my eye that I
can't identify however.
It's a Quad-Height board with a 50-pin connector on it There is one chip
with a Model number on it "UTS25". The board looks to be manufactured by
either MTI or MT, not sure which. The one EPROM says "MTI-U/B A3.4". It
has a Z80B CPU from SGS, and a Zilog Z0853606PSC chip. However the chip
that really caught my eye was a WD33C93-PL. Could this be a fabled SCSI
controller? The WD chip is the same as an Amiga 3000's SCSI controller.

Sure is. Sounds to me like you got lucky! That's WD's SCSI
chip, and it can be either a single-ended or differential interface
depending on the line drivers used.

And is also incorporated in their old WD7000-ASC SCSI cards.

Ditto here, this is on my Always IN2000 card. Very quick if done
right and can do sync transfer pretty good.
