Can't speak for Alliant but Masscomp and DEC had shared authorship in he
diagnostics group. The former in C and later in BLISS of course; but the
authors were pretty much the same. If it works, don't mess with it. Also
the Tech's were all originally ex-DEC so it made sense - although the
manufacturing guys were ex-DG.
Actually there was a story I tell. Both Masscomp and DEC were using the
same HW CAD system at one point. DEC has a microcode assembler that had
originally been written in PDP-11 assembler and was running compatibility
mode on the Vax. Masscomp wrote a new microcode assembler that was
"frighteningly similar" in C that tjt the UNIX guys put together with
lex/yacc and the like one weekend for the HW team. Knowledge of this made
its way to the mill. It was also know that DEC has a number of CAD
libraries that the HW guys had been using to make their board layouts
easier -- discussions occurred over beers at the Mau Kaui... tapes some
how fell out of cars one night... and DEC had a microcode assembler running
on Ultrix in C and somehow our HW guys stopped complain about some missing
libraries they wanted.
