Found the 6-level TTS code at

The code still uses LTRS/FIGS shift, but now it changes between upper &
lower cases. The first 5 bits are the same as ITA2. The 6th bit gives
access to numerals, punctuation and other special characters.

What was the timing of TTS? Is it the standard 22ms bits & 31ms stop  
for a
8.42 character??

strip off  the "shift" bit, it could be copied on a 5-bit machine.
