Alas at the momnet (just come out of hospital, hence the absnece from
this list for a couple of weeks), I don't really feel like climbing over
the VAX rack to get to them...
I will have to dig out the
schematics sometime (yes I have the full manuals...)
I thought if anyone had details on them it'd be you :-)
(Aside - does PERQ stand for something, or was it originally all
capitals just as a trendy marketing thing?)
No, it was claimed to be an acronym : Pascal Evaluation Real Quick (or
Really Quickly).
The machine, remember, was intended to run Q-code (a bit like UCSD
p-code, but with some graphics instructions) as its machine code...
I would start, though, by checking the 55V line
from the PERQ's PSU to
the monitor. If that's low or noisy, you'll have all sorts of problems...
Rats, I did last weekend and it didn't seem *too* low but I haven't got
the exact figure with me at the mo. I believe it was sitting at 50V or (does appropriate media exist out in the public domain
to rebuild the
hard disk contents if needs be? Of course finding a replacement drive if
that breaks is another matter entirely)
Public Domain, not as far as I know (I am not sure who owns the copyright
now). Exists in the hands of enthusiasts? Yes, most certainly.
