This real time clock stuff reminded me of the work I did using a
GPS receiver as a clock source for various Unix machines.  The
same could easily be don for the COCO except for the limited
number of available serial ports.

So, now the question.  Has anyone ever made or even considered
a serial pack using the 16550?  It offers speed and efficiency
and could probably be made addressable so that one could put a
number of them (well, a couple) on a COCO allowing for even more
fast serial connections with lower CPU overhead.  Seems like it
would be nice for DriveWire.  Hmm...  Now that I think of it,
you could probably make a board with more than one and add a
bunch of serial ports.

Any serious flaws in this thinking?
