I think I learned about it through this list, but
I could be mistaken.
List, what do you say? But wouldn't I then need a clip-on piece on the
D-subs for those annoying DEC
modular plugs?
If you wanted more TTYs than the console, perhaps. Worst case, I suppose,
you could build a level-converter board with a MAX-232 chip or 1488/1489
or whatever (DEC also used 9636/9637 pairs IIRC) to go from the D-subs
at the edge of the board to something more standard (the 15-pin connector
does have two 3-wire serial connections - that clip-on piece converts them
to RS-432 over DEC-MMJ)
And there's still the power question.
True. AFAIK, DEC used one type of PSU for all those cases, so the supply
for an external RD54 or TK50ZFA could do the trick.
It's a bunch of work, I'll admit, but it depends on how badly you want
a VAX and whether or not you have alternatives. I certainly wouldn't
do it if I had another VAX that worked.
