[Hallicrafters] Key / Paddle / HA-1 keyer.

[Waldo Magnuson]

The HA-1 keyer is set up to use a paddle (which I have).  I would also 
like to use a straight key (which I also have).  Has anyone ever made a 
modification to the HA-1 so that either device could be used.  I'm 
thinking of a switch and key input on the back (no drilling so it could 
be restored to originality).  Comments solicited.  Thanks.
