	Ok... found a card... I don't really know what it is.  It was
in the back of a Sun3/260 (or something similar... there is 4 meg on
the CPU card ... but it's the same chassy as the 3/260).  It is a VME
card ... or maybe more properly a Multibus card (as it only has two of
the three connectors).  The components are far too new, however, to be
Sun3/260 or even Sun4/260 vintage --- there are lots of tiny surface
mount and PLCC chips.

	There are 5 connectors on the back.  One connector is larger
than the other four and looks like the tiny-style SCSI connector (HP
and Sun use them, I believe).  By my could-be-wrong count, it has 60
pins.  The other four connectors are the same style with only 26
pins.  The back of the VME board is cut out to let round cables pass
out of the machine.

	There are 2 xylogics chips on them.  One VMEDMA 176-120-001
and the other REGCEL 176-121-001.  The other large PLCC is LSI LOGIC
L1A4378.  What looks to be a ROM is (c) AMD and labelled 27C256 on the
chip and E2271 2.2 // 5763*753 on a label on the chip.

	An interesting feature of the board is that there are dozens
of terminating resistors on it... many dozens.  There are also 4 large
very well heat-sinked devices that I suspect are transistors.

	The back of the board is labelled with two stickers.  One
X9420849 and the other 753-107-216 // B-D-2.2

	The front of the VME holder for this card (it's really quite
small) is labelled with Integrated // Resources // Model
No. 0961FB5XYL // Serial NO. 387 // made in U.S.A

Dave.
