If you really wanted to push this forwards, write me
some MSCP
controller firmware for an Atmel microcontroller...
I have the skillset to do
this. What I don't have is the
documentation that would allow me to figure out how to talk MSCP and
bit-bang Qbus. I've seen doc on MSCP as implemented in device XYZ
in device XYZ's
manual, for at least one and I think two values of XYZ (UDA50 comes to
mind). I don't think I have any of the relevant manuals, but bitsavers
or vt100 or some such surely has at least one of them.
Bitsavers has AA-L619A-TK_MSCP_BasicDiscFnsV1.2_Apr82.pdf,
AA-L620A-TK_StorageSysDiags_1982.pdf and
AA-L621A-TK_UnibusPortDescription_1982.pdf at
http://www.bitsavers.org/pdf/dec/disc/uda50/
I'm not sure if these are the scans I did five years ago (the file dates
are later) but they're the docs you'd need.
