I've searched in all the usual spots and haven't been able to find a
CMD CQD-240/243 manual. It is a Qbus controller with both single-ended
and differential SCSI capability.
It looks similar to the CMD CQD-220 (manual on bitsavers) and the CMD
CQD-720 (manual on bitsavers) - but has a different switch
configuration with more options.
Regards,
Lyle
