Tony, and all,
Again thanks for the good counsel. The basic PERQ passed each phase
of checkout testing just fine. The monitor and keyboard both had issues
Excellent. At least you don't ahve a PSU to rebuild... That's not an easy
job. Repairing logic boards which you also don't need to do, is actually
quite fun :-)
. For the moment, I've swapped in working items,
while I look through
I will forgive you -- jsut htis once.
What are the problems with the keybaord and monitor? I have the official
scehamtics for the latter and a hand-traced set for the former. I am sure
we can et those workign too.
those issues. With those in place, the system booted
right into PNX.
Basic UNIX operations ran without a hitch. I've not located the right
archive box for software yet, so that will have to wait for another
weekend. There's also problem of cable insulation peeling off on the
'good' keyboard and monitor leads. That too gets queued for attention.
Yes, that's another proble,. It happens to these old cables, the outer
jacket gets stiff and crumbles. Fortuantely there's a screening foil
under it , so the cable is still just about useable.
Remplaicng hte cabel, or sliding sleeving over it is not easy. The D
conenctor is oen of thsoe oens with crimped pins put into a housing. If
you nake it apart, for $deity's sake make a ogod diagram of what goes
where. Replacing the cable, at leeat the monitor cable, would eb fun too,
from what I remember there are tewised pairs in it.
But all in all quite a successful outcome. I will
keep interested
parties posted. If you want to see this system, it's in TNMoC's
multi-purpose/scientific computing gallery.
Although IMHO PNX is the least intersting of the PERQ OS's (there's not
that much that is PERQ-specific in it), it's probably the most
appropriate for an ICL exhibit.
