A question about MSCP/TMSCP:

I managed to grab a VAX with a bunch of qbus boards in it, among which was a
TK50 controller and a CMD CDQ-220 (SCSI adapter).  I know the TK50 is TMSCP
compliant, and the CMD board says it's MSCP or TMSCP (not both at the same
time) compliant.

So my question is - where exactly does the MSCP protocol fit?  Is it a
protocol used to communicate to the controller, or is it a software access
layer which provides a common API to the driver subsystem?  If I have any
MSCP compliant board, would it automatically work if NetBSD supports MSCP
boards?

Thanks.

BTW - this machine also has a Dilog DQ256 (SMD controller) and a Dilog DQ152
(1/2 tape controller) which I will most likely not be using.  If anyone has
a need and can aide in reconfiguring my system to be sans DQ256 and DQ152,
drop me a line and I'll ship 'em out to ya.
