I've been working on an MSCP controller

https://github.com/livingcomputermuseum/UniBone).
It'd be nice to extend it to do TMSCP as well. Is there an equivalent to
the "MSCP Basic Disk Functions Manual" (AA-L619A-TK) for TMSCP? I can
probably glean most of the information I need from various *nix device
driver sources out there, but it'd be nice to have the definitive reference
on hand, and so far it's been eluding me. But maybe I'm just not looking
hard enough...
Thanks!

The protocol specification for MSCP and TMSCP is available here:
http://www.bitsavers.org/pdf/dec/dsa/mscp/
You might also want to look at the implementation of MSCP and TMSCP in Simh:
