[GreenKeys] ROTRs and Model 35 machines

[Don Robert House]

Larry,

Several versions of the 35ASR were available.  On some of our private  
line versions a stand alone Receive Only Typing Reperforator (ROTR)  
was plugged into the ASR with a long cable.  The ROTR could be turned  
on by pushing a key or with a code in the typing unit stunt box.

In addition to this variant, the 35ASR itself can be put in a tape  
only position for sending (TTS) or tape only receiving (TTR)
In Illinois Bell every single 35 ASR we installed had a typing  
reperforator in it.  If the customer did not pay for the option we  
disabled the printing and removed the ribbon.

Occasionally there would be an odd ball arrangement (special design)  
where a stand alone ROTR would be connected to a 35KSR or a 35RO but  
very few of these were in our district of 600+ machines.  The problem  
of course using a ROTR for cutting tapes is that there is no way to  
backspace the reperforator if you make a mistake.  Most tape cutting  
applications used the 35 ASR or an off-line 35 KTP (Keyboard Typing  
Perforator)

I can send you images of these variants if you would like to see images.
