Bringing a Decwriter III LA120 back to life here and it's the first one
I've worked on. Mechanically and cosmetically its in great shape but
unfortunately, power on yields flashing "8" on the LED display.
According to the technical manual this means "Microprocessor Failure".
Hmm. Seems there's enough of a microprocessor there to get the display
running and flashing 8 but apparently not enough to be a printer.
Any words of wisdom as to likely suspects in this failure mode?
The technical manual is great-- with lots of tests documented and scope
photos etc so I'll eventually get there but of course I am looking for
any hints as to common failures that others have already dealt with.
Thanks.
Chris
