I’m weak in my DEC history and collection but I’ve heard some in person

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.
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.
