[net.micro] an old idea whose time has gone

Ah, here's my chance to tell a story I've always wanted to post:

About 8 years ago I worked in a computer lab in the math department at
UC Davis, where we had a DG Nova with a teletype as the only terminal
and printer.  We too tried putting an AM radio on top, and found that we
could control the output frequency by adjusting the length of a short
loop, and wrote simple music programs to show it off.

We then realized that we could use this technology to drive a 300 baud
modem, and thus interface to a real printer across the room (part of
another system).  Believe it or not, it worked, and we routinely used
this "wireless" interface for some time.
