Anyone owning the service manual for an ADM-5?
Seems like this terminal is not as common as the ADM-3(A).
Couldn't find it on bitsavers or anywhere else :(
I'm looking for one too. I did find the service manual for the ADM-3A (on
bitsavers I think) and some of the ciruitry is similar or the same so it might
be of some use to you.
Yes, we got an ADM-3A here and I know that there are similarities.
Anyhow, it's not the same. Reassuring the details und finding out
the differences often is a lot of work.
Unfortunately, the fault in my ADM-5 appears to be in
a part of the circuit which they do not have in common.
I wonder was the ADM-3A more common though?
I think so. The ADM-3A is documented well and you can find much
references and images of the terminal itself and its circuit board
in the web, in contrast to the ADM-5.
Ok, probably this is because of the ADM-3A being much more popular
because of it's historical impact on the Unix history and the
origins of the vi editor.
In the college where I came across
them, there was row after row of ADM-5 terminals but only a single ADM-3A which
nobody liked using, mainly because there were difficulties clearing the screen.
But 25 years later, there is much discussion of the ADM-3A and everyone seems
to want one while the ADM-5 barely gets a mention.
