Teletype did indeed make their own ICs and they did indeed mark them  “TTY”
. My first assignment as a co-op in 1973 at the T7 R&D facility was  to 
profile PN junction depths on diffused wafers. The R&D fab was on the  first 
floor of T7. Just off the T5 cafeteria was the epitaxial deposition lab.  The 
PMOS manufacturing facility was on the north side of T3. 
 
TTY custom ICs went into the model 43, the model 40, and certainly other  
products that came after my time there.
 
The initial process was P-channel and they did eventually make N-channel  
devices.
 
Tag Waggener was a WECO guy that came to TTY in ‘73 to lead the effort.  He 
chronicled it in “Teletype, We made That Data Move” (self-published on  
lulu.com).

Did Teletype eventually have  their own ICs?  I suspect someone else
would have designed them for  them and then Teletype put their own label
on but this is the first I  have heard of "TTY" ICs.

One theory is they are from a model  43...??
