but I
cna';t believe it's beyond me to work it out :-). Do scheamtics
of the frontpanel boards exist anywhere, for example?
I did mod a panel once back when I was in DECpark. I asked around
and someone in TSC had the schematic, so it was pretty easy to do.
I almost certainly have that schematic somewhere so it undoubtedly
exists; the question is could I find it before anyone manages to
reverse engineer the (fairly simple) schematics :-) From what I rememebr the switch PCB doesn't have
much on it, and I doubt
it would tax me too much to trace out a schematic. It must
be easier
than some of the things I've done, for example...
Actually, I suspect it's one of those units where it's quicker to trace
out a schematic than try to find out. [I realised years ago that for many
things it was quicker nd less stressful to reverse-engineer schematics
than to try to convice the manufacturers to sell me a service manual]
Undrotuantely the only BA23 I own (which contains a MicroVAX II GPX I
think) is hinding behind a MINC-23, a PERQ1 and assoreted smaller
machiens. Otherwise I'd regard producing schematic as a pleastant
diversion for half an hour or so...
