Eugene,

The TT-235 is a stand-alone, 5 bit tape reader, but unlike the more 
standard versions (TT-122 with Synchronous motor or the TT-123 with 
series governed motor), the "TT-235 is equipped with a remote control 
facility to enable it to transmit one character at a time on demand, or 
operate like the other models in a free running mode." (from KLI 
Catalog, Feb, 1970).  I believe this remote control function was to 
allow it to operate with certain encryption equipment.

It also generates a 7.00 unit code and is "Baud rated" ie, the catalog 
says it will operate at 45.5, 56.8 or 75 bauds with the proper motor 
gearing.  The similar TT-122 & 123 are rated in WPM at 60, 75, & 100 wpm 
with the same sets o f gears.

It is a stand-alone unit, not part of the AN/FGC-25.

73,
