We had VMS source on microfiche as part of he support contract. If you payed more you
could have got it as machine readable.

Seems like yet another mediocre UNIX port at
first, but then they happen to find the system schematic netlists and PAL equations in
addition
to partial source code on the hard disk. If those are published that will make a quite
wholesome thing to study.
I tried to stress on their discord that finding things like that 40 years out is a very
unusual occurence.
I've spent decades digging through people's garages trying to find stuff like
that for bitsavers.
I’m weak in my DEC history and collection but I’ve heard some in person stories that VMS
source was not impossible to find on microfiche at certain institutions. They might have
had at least board level schematics too. That situation would be roughly equivalent to
IBM mainframes through the 1980s but you’d still be missing a lot of microcode and logic
equations to zoom in at any level for these two examples.
Are you aware of anything else where the whole kit and caboodle is available?
Particularly keen on microcode and logic equations since that stuff is indeed hard to come
by.
