That SPF shows a date of 1987.   Masscomp was '83 for the FP and 84 for the APU and I know we could not get them - but then again KO was mad at us.  At that point we had more of the 780 HW guys then DEC did, plus a bunch of ex-VMS and ex-LDP folks.   The nasty-gram letter from Ken was framed and hung out the office of one of the VPs (I wonder if Palmer of one of the other Masscomp pack rats still has a picture of it).

I know we tried to get it for our Vax, and it was a clear - no way.

BTW: the 780 & 750 had ustore but it was not user documented and the tools were internal.   Paul Guilbo wrote much of both and later would write the uCode for the Masscomp FPU and APU.   Paul was bitching about the great tool(s) they had had at DEC, so one weekend two of us on the SW team got sick of his bitching a couple of us hacked up a uCode assembler in the same key in Yacc/lex/C (not BLISS ;-).

Apparently they were at least advertised as available for the 780.
