Reviving a Letterwriter 100 (LA100)
I recently inherited a DEC Letterwriter 100 (LA100) KSR which is
unfortunately all but dead. I'd like to restore it to working order.
When powered up, the paper-feed motor buzzes for a second or so and the
CTS and LINE indicators illuminate. There's no carriage movement
whatsoever and the keyboard doesn't seem to do anything. The unit is
supposedly meant to flash all its indicators when the power's turned on,
but this doesn't happen either.
I've opened the thing up and verified all voltages from the PSU are ok.
I've also checked the indicator LEDs themselves and all are working.
Disconnecting cables from the main PCB hasn't revealed any obvious
culprits, so I'm at a loss as to what to try next.
On the documentation front, I've found the Terminals and Printers
Handbook (1983-84) and the Illustrated Parts Breakdown, but these are
both of limited use in my case. I could really use a service manual or
some tips regarding how to proceed.
Any pointers or ideas would be most welcome.
PS. I also managed to mangle a couple of the plastic lugs used to hold
the covers together whilst dismantling it. I don't support these are any
kind of standard part of which someone may know a supplier?

Get a second one, and maybe a third or more. Which one will end up as
the "parts" machine, I can't say.
While its true that "you can't fix stupid", apparently you
can package it up and sell it. -- fnorgby on TMBO
