Yes. Thanks Tony. I've been there and had a look (and in fact, I also
have model 745s for which those documents apply) but the 725 is quite
a different beast.
At this point, I have no specific failure to fix, other than a totally
disintegrated timing belt that drives the paper advance. I've never
seen a belt fail this extremely-- all the rubber is gone and all that
remains are the fiberglass threads, still wrapped around the timing gears!
It's like some alien rubber eating bugs devoured most of the belt :-)
I went looking for any documents on this unit again, with a small hope I
might find some p/n or specs on said belt. I have been able to deduce
most of the parameters by inspection though and have a couple belts
coming, one of which should be a good fit.
So, now I just want the service docs for the collection, to go along
with the machines.

Is anyone aware of the existance of a maintanance / service manual for
the old TI "portable" data terminal, model 725?
Note that is is one of the very early (and very large) thermal printing
terminals from TI,

I have several here that I am trying to keep running but have never
had technical information that would include schematics or other
parts information.
There's a service manaul for at least one Silent 700 on bitsavers. It
contains scheamtics, but they are none-too-clear. But it might be a start
for your unit, even if it doesn't driectly apply.
