Recently I acquired a CP/M system made by a company called Dynabyte,
this system is a Dynabyte model 5200; unfortunately, instead of using
standard format 8" disks, it uses 5-1/4" floppies which appear to use a
format which is incompatible with that of any other CP/M systems that I
know of.  In addition, to make matters more difficult, there were no
communications, or file transfer, programs on any of the diskettes which
came with the system.  I was going to attempt writing a com program for it,
but it appears to have a non-standard UART (I'm guessing that this chip
is the UART, since there are two of these chips on the CPU card and they
appear to be connected to the serial port connectors); the chips in question 
have TMS 5550 marked on them (if I recall correctly from when I had the
CPU card removed from the system).

Is there anyone out there who is familiar with this system, its UARTS,
or who has any ideas about how to get a communications and file transfer
program set up and running on this system?  Thanks in advance for any
information.
