Nick,
Great job! What an impressive demonstration. Makes me want to get my  
AN/TGC-1 operational!

For your amusement and edification, here is a quick and dirty demo of the  
Manual Tape Message Address Segregator I have been working on.

Thanks to Doug Hensley  and Jim Haynes for the equipment and docs and to 
various greenkeyers for  advice and help. This afternoon I finally got past 
finding problems with bad  diodes, bad relays, and bad relay contacts, and 
fired up a working  system.


This device takes a formatted message tape with multiple  destination 
addresses and turns it into separate message tapes for each  addressee. It 
consists of a relay logic panel, tape reader, monitor printer,  and up to 8 
reperfs (I have 3 hooked up). It all runs at 107wpm.

To do  this, relay logic recognizes character sequences for Beginning of 
Message  (ZCZC), Start of Address (FM), the end of the From line (CR/CR/LF), 
the end of  each addressee line (CR/CR/LF), and the body of the message  (BT).


Since it is a manual segregator, the tape halts at the  proper times to 
allow the operator to turn on/off the appropriate reperf for  each addressee 
line. So the end result is multiple message tapes, each with  only a single 
addressee shown.


If you'd like more info, the  description is at

Dang, those Teletype engineers were wizards!

Thanks for the help  and encouragement. What a great group.
