Versatec
PDP-11 Matrix control
This is a dual height board, but I'm pretty sure it's for a UNIBUS system,
thanks to the wierd connector sticking out the side of it for another board.
Yeah, connectors out the side almost always signals non-Q-bus. This
is part of the set that runs (surprise!) a Versatec plotter - think of it
as a really labor-intensive laserprinter and you won't be too far off.
DILOG DQ342
Quad Height, has a 34 and a 10-pin connector
I think this is a MSCP MFM disk controller (there was also a floppy-only
version.)
SCD-RQD11/EC
Quad Height, 4 20-pin connectors, 1 34-pin, and 1 10-pin. 3 LED's 2 green,
1 red. I think it's a Sigma ESDI controller, based on doing a DejaNews
search, it also looks like it _might_ be basically a rebadged WQESD
controller, since the one article talks about WOMBAT. Is this correct, and
can I just use my WQESD manual for it?
The WQESD is the same as the SCD-RQD11/EC is the same as the Qualogy
equivalent is the same as the DSD equivalent is the same as the American
Digital Equivalent... *All* designed by Webster out of Australia.

Count the chips, identify their type, and you know the size!
