Cool, this is the one that has Bubble Memory storage
so it is quite a
find, if I didn't have two already I'd be interested :-). Did you get a
manual with it? That is what I don't have and so only know about have
the commands for the thing. I have a bubble unit (these could hold up to
three) that I'd be willing to part with if you find a taker.
It never ceases to amaze me; just when I thought I knew all the Silent 700
models, someone comes up with a variation I haven't seen.
Further, the TI printheads don't get
"dirty" they get "broken" They are
thermal and thus limited in the number of characters they can print. Out
of a lot of 36 silent 700s I picked up (for $25!) only 9 had working
print heads and most of the others had had their print heads scavenged.
You can get "new" or "refurbished" replacement heads for about $90
on
the net though.
My latest Silent700 is a Model 735 KSR. The carrier for the print head
was broken, but repairable, as was the mechanism for adjusting the print
head pressure against the paper. After making those repairs, I had print
quality similar to what was shown in the last picture. However, some
judicious adjustments cured that, and it now prints fine.
Additionally, the TI Silent 700 Service Manual I have does describe a
procedure for cleaning the print heads. IIRC, you take a sheet of
plain, regular paper, soaked lightly in alcohol, and run it through
the platen, then type on it. The alcohol may be a figment of my fatigued
imagination; but the procedure isn't.

Anybody have any interest in a TI Silent 700 terminal? I just
rescued one from a local shop. Even has about a third of a roll
of thermal paper left, and appears to work fine (other than needing
the printhead cleaned). Has clamp-on cover with handle, too.
From the back info plate:
765 PORTABLE MEMORY TERMINAL
Part No. 099230-0001
Serial No. 0476617603
Volts 120 VAC
Freq 47-63 Hz
Amps 2.0A
Watts 150W
Inside the unit is a sticker that says it came from
Data Access Systems, Inc. in Houston, with a warranty
sticker, model/serial #, and an "80K. MEM KIT II"
notation.
I've got pictures of the unit up at http://www.decvax.org/ti/
I even found the original 1971 press release about the
Model 725:
http://www.ti.com/corp/docs/company/history/silent700.shtml
If anybody is interested in this terminal, please let me know.
I'd like to see it go to a good home, and the SO wont let
me have anything else for a while (she's still getting used
to the VAX 6000)...
