[GreenKeys] Mystery M33 UCC...

[Kenneth Gartland]

Teletype produced so many variants of the M33 Universal
Call Control units as required by their customers...

Many were modified substantially by the customer
to accommodate hook ups to computer interfacing...
The DC ones were fairly straight forward, but the RS232 to DC
or DC to EIA were more difficult to work with...
Most times, the documentation pkg(s) were missing, especially
the field mods done by the computer techs...

This particular one, I can't identify, but am sure it is a nonstandard
run done for a computer company...

At the bottom of the UCC chassis, under where
the pc boards are mounted, there shud be an I.D. tag present
which will indicate this 'Original' version of this UCC before mods
were made...

In a case like this, it may be easier to 'Reverse engineer' the
UCC, to a more 'Standard' one such as the UCC6...

I am sure there must be a few UCC6 or UCC28 kicking around...

Back in the day, the UCC28 was the one most favored
by computer suppliers as I/O terminals...

Hopefully, Julien can locate a document pkg or wiring
diagram set...

Best of luck!
