          I am looking for a CP/M system that can be run completely from an
          external  terminal.   I  want  one  with  either 5.25 or 3.5 inch
          disks.   I would also be interested in systems that have at least
          two  rs232 ports.  That way I could change things around so as to
          avoid  using  the  CRT.   I  have a friend who wants to hook up a
          braille terminal thus a CRT is of little use.

At this installation we have quite a number of Morrow MD2/MD3 systems using
external  CRT's  as consoles.  The MD machines are designed to operate that
way;  i.e.,  the  console  is  an  external terminal device attached to the
mainboard via a standard 232 interface.  The complete MD package included a
terminal  sold  by Morrow, but we purchased only the boxes and used our own
terminals.  It has proved to be a very workable arrangement.  We use CRT's,
but  any  232 ASCII device could be attached to the console port (a braille
device,  for example).

The  MD machines are 64K, Z80 CP/M devices with 5.25 inch disk drives.  All
of our machines have 2 drives, but the hardware, as shipped, will handle up
to  4.   The  systems have two 232 ports, one for the console and one for a
serial printer or modem.

Unfortunately,  the MD series is no longer manufactured.  I understand that
that  Morrow  is  in  Chapter 11.  In any case, they ceased producing 8 bit
devices  several  months  ago.   Still,  there  are a lot of MD devices out
there;  you  might  be  able  to  obtain  a  used one.  I think it is to be
recommended for the application described above.
