The protocol specification for MSCP and TMSCP is

You might also want to look at the implementation of MSCP and TMSCP in Simh:
https://github.com/simh/simh/blob/master/PDP11/pdp11_rq.c

Not so useful for tape, but the original MSCP reference which Josh
referred to, the "UDA50 Programmer's Documentation Kit" (QP-905-GZ
comprising AA-L619A-TK, AA-L620A-TK, AA-L621A-TK), is on Bitsavers at
