Subject: [TUHS] Why did PDPs become so popular?
Date: Sun, 31 Dec 2017 12:20:06 +0700 [thread overview]
Message-ID: <CAMYpm85uJvDK6rdKUu9G5hDFThtuTv0tJRmUbw-MjJe0774e_w@mail.gmail.com> (raw)
A bit off the PDPs, but to do a minor correction on mail below
The commercial version of 'UNIX' on Alpha was maybe first called
Digital Unix OSF/1, but quickly changed to Digital Unix at least with
v3 and v4.0 (A - G). From there we had a 'break' which only in part
was due to take over by Compaq and we had Tru64 UNIX v5.1A and V5.1B.
The V5.1B saw updates till B-6.
As for the Digital C compiler, I'm still using
DTCCMPLR650 installed Compaq C Version 6.5 for Compaq Tru64 UNIX Systems
When I get some old source (some even developed on SCO UNIX 3.2V4.2) I
like to run it through all compiler /OS-es I got handy. With the
Compaq C compiler and HP-UX ANSI C I mostly get pages of warning and a
few errors. By the time I 'corrected' what I think is relevant some
nasty coredumps tend to disappear :-)
Compile for a better 2018,
