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.

RQZX1, which talks both SCSI and floppy.  I've never seen one.  Someone once
told me that they didn't do MSCP 
 which caused me to lose interest.  But if they do, I should keep an eye 
 out for one.  The usual resellers seem to think they're made out of 
 solid Rhodium. 
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.
