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