As far as I can tell, it doesn't.  The only TMSCP device I see is

mtc*		at uba? csr 0174500	# Tape MSCP ctlr

Since there's no other mtc in sight, I rather wonder why it's mtc*
rather than mtc0 - perhaps for machines with multiple buses?

I imagine you could add a second mtc line to your config at whatever
address you put your Dilog card at.  ISTR that DEC had a bunch of rules
for such addresses - the phrase "floating CSR space" comes to mind -
but I don't think anything keeps you from putting it anywhere as long
as (a) it doesn't overlap with any other device and (b) you tell the
kernel where you put it (in your second mtc line).
