[GreenKeys] RPE28 Reperforator

[Duncan Brown]

"Real teletypewriter operators don't need the message printed on the 
tape, they can read the hole patterns!"

Roy,

I assume you are talking about the "Single Magnet" reperforator 
(Bulletin 147).


It only perforates the tape, there is no typing.  The typing function 
was probably not considered necessary for the designed application 
(message relay/storage) and it simplified the design considerably.  This 
was probably the first serial reperforator that Teletype Corp made.  The 
"Single Magnet" name was to differentiate between the earlier, multiple 
magnet units, that were multiplexed using parallel transmissions.

I have also seen a picture of the more "Standard" M14 type basket typing 
reperforator mounted in the same domed cover  for use with the M19.  
Later the M14 was mounted on a shelf above the TD.

I have never seen or heard of anything that would read a tape and then 
type on it.  If you needed a typed copy of a tape, you just put it into 
the TD and had it type out on a printer.  Otherwise, you just read the 
hole patterns.  In the Army, all the TTY operators learned how to read 
the tapes. (As a TTY repairman, I only learned a few of the patterns, 
such as RY, LTRS, Figs, CR, LF, etc.)

Have fun,

Duncan
