I'd completely missed that directory on Bitsavers (thrown off by "dsa" I guess) and nothing turned up in my various searches. And I've been referring to SIMH from time to time on some of the shadowy corners of the spec, but having the real spec on hand helps put things into context. Thanks again, - Josh

TMSCP docs?
I've been working on an MSCP controller implemented on top of Joerg Hoppe's Unibone and that's been going fairly well, modulo a few oddities here and there (if you have a Unibone and want to beta-test it, it's up at 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! Josh
