[Coco] COCO 3 for LowFER transmitter?

[John Donaldson]

Hi James,
   At one time I had a COCO program that used the cassette relay to key 
a rig on CW and the
cassette port to receive the incoming CW signal, translate it, and 
display it on the screen.  I used to
have a lot of HAM related program for the COCO, back when I still owned 
one. Later when I
got a MM/1, I used to run a version of KA9Q with packet and that was a 
lot of fun.
