Well- my terminal (Altos III) was a bit too
unobtrusive, and wound up being left on for a couple
of weeks
straight. Now, it has a somewhat anemic beep and the
screen comes up with garbage.
Looks like possibly a RAM issue. Anyone have
experience or ideas?
I'd start with checking the power supply - IIRC those
Altos terminals were mostly rebadged Wyse terminals.
Check the power supply voltages and reseat socketed
chips. When you say garbage - are you still getting
the status line with garbage text, or is the entire
screen covered in garbage? Or, are elements still
there but displaying wrong, I've had character roms
fail or chip-creep out of sockets and do some strange
things.
The anemic beep kinda hints toward the power supply,
it could need capacitors, I fixed a Honeywell terminal
that would give an anemic beep and no display by
replacing the filters for the logic supply.
Good luck!
