For various reasons, (mostly to share access to an FPS-164), we
want to get some medium speed communication (say 10KB/sec, minimum)
with a Honeywell CP-6 system.  The Honeywell may eventually support
ethernet, but in the meantime we want to throw something together
(at a reasonable cost).

One possibility is a Danford Serial expansion board.  They claim
that the interface will support 16 serial lines in parallel, each
loaded 100% at 9600 baud. The Honeywell side can probably do better.
If it doesn't cost too much to rip files apart, send them as 16 parallel
streams, and re-assemble them, it looks do-able.

Questions:
   1. Has anybody had this sort of experience with the Danford boards.
      Will they really run at that speed dand leave any cycles left in 
      the DSP-80 (or perhaps, DSP-90)?

   2. Any other ideas on how to do this?
