Way cool, Noel.  And thanks all for your suggestions.

Hendrik:  I too remember using a KSR-33.  KSR = Keyboard Send  
Receive.  ASR = Auto Send Receive.  As far as I can tell, the ASR

ever used had that, so I guess they were ASRs.

I remember how I used to think those teletypes were marvels because  
they could type so much faster than I ever could.
That reminded me of Chuck Adams, morse code communicator extraordinaire.
