DEC used to fob us off because we ran Unix; it was only when DECEX became
available that the overlapped-seeks issue on the RK-11 was finally
acknowledged, as RSX/RSTS didn't use that feature, and MAINDEC didn't prod
it.
That was the story of my life running the UNIX machines, not only from DEC and
other
service guys but also the manufacturers themselves. Sometimes I had to bluff and
say i was experiencing the problem with the proprietary OS. I had to remember not
to use our slang for the other OS’s (both HP’s MPX and Gould’s MPE we referred to
as Might Pour Excuse).
