Hi all --
The lovely HP 3082A terminal I've been using with my PDP-11/73 has
started exhibiting odd/annoying behavior today. The 3082A is also known
as the "Industrial Touch" terminal, it's a compact unit in a rugged
housing with an EL display, built in keyboard, and a touchscreen.
At powerup, it normally gives a few short beeps and starts normal
operation. As of today, it gives one continuous beep for 31 seconds (I
timed it), after which it works fine -- until the next time it needs to
emit a beep (a ^G, for example) and then it beeps for 31 seconds again.
This is, to be quite honest, intolerable :).
The manuals on
hpmuseum.net are limited to configuration/user manuals
and the brief troubleshooting it recommends actually *does* mention the
continuous beeping symptom, but gives no suggestions for causes, and
suggests as a fix to (a) try turning it off and on again (I've done
that...) and (b) replace the terminal (can't do that). I've also tried
resetting the terminal config (hold down Help + . at powerup) and this
has no effect. The terminal passes all built-in self tests.
Anyone happen to have any experience with these, or know where a service
manual might be found? If I at least knew what the 31-second beep
signified I could start looking...
Thanks,
Josh
