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,

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.

>Plessey
>P/N 705920-100A
>Quad Height, RAM board

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