True. About pendantic, I don't know... TMSCP and MSCP are very similar,
but there are few differences as well. The device drivers usually share
the port code part, and just have a different "upper" end.

I have one. They talk MSCP and TMSCP. They have SCSI and a floppy
interface to connect disks. It's a quad card, so bigger than most other
SCSI controllers out there for Q-bus, but it's nice.
