I made a trip to my (far away) storage locker today, and brought
home a few things that I hope to bring back to life in the coming weeks.
First is an HP9810A. I just powered it up...Several LEDs turn on
immediately, but the display is blank and the keys are unresponsive.
Does anyone (Tony?) have any troubleshooting hints? Are schematics
for this machine floating around anywhere?
The second is a PDP-11/05. It hasn't been powered up in about
twenty years, and has an empty backplane. I'm pretty sure I have all
the right boards, but I'll have to dig through quite a few crates to
locate them. I may do that tomorrow or Friday. Friday is my
birthday (39, *shudder*) and I always make it a point to do things
that I love on my birthday, and hacking on a PDP-11 definitely
qualifies, so I'll probably work on it then.
The first thing that sticks out about the 11/05 is that the
keylock switch has a key broken off in it. At least it's in the
"power" position. Does anyone have a spare key for this machine? If
so, can I talk you out if it? It's not one of the ubiquitous XX2247s
of which I have quite a few; it's a standard "slot" key.
Thanks,
-Dave
