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: https://github.com/simh/simh/blob/master/PDP11/pdp11_rq.c https://github.com/simh/simh/blob/master/PDP11/pdp11_tq.c Matt
