On  the AN/TGC-1, I think the "flip-flop" operation  was standard. This 
allowed outgoing messages to always be queued up ready to go. (I was 
trained on the AN/TGC-1 fifty years ago. I don't think the Army was 
still using them in 1967, but it was probably a good introduction to 
tape-relay equipment.)

Have fun,
