  Before leaving the RX01 topic, note that Chuck's
design was implemented
 using the Cadsoft Eagle years ago and is available at:

 A minor update is at:

Thanks for those.

  The idea of putting an SX-28 processor in control of
the communications and
 using a native USB interface resulted in the (untested) derivative design

I'll have to look at that.  I have, in hand, an ATMEGA8 bridging USB
to a textual LCD panel for LCDproc / LCD4LINUX, etc.  The USB
implementation is in software, keeping the project cost quite low
($3.25 for an ATMEGA8 in low quantities, AFAIK).  I might have to see
if I can take what you have there and see if an ATMEGA8 can do it,
too.

I hate the fact that the parallel port is vanishing, but since I can't
keep it from happening, I might as well attempt to keep classic
peripherals working with hardware that's out now and in the near
future.
