I want to design an application system, on which using a 286 or 386 machine,
and use several terminals and printers connecting to the machine. Anyone
from a terminal can access the database on computer at the same time and
can print a record to his/her own printer. Maybe 6-7 terminals and printers.
Now my question is:

1. what kind of machine should I use, 286 or 386?

2. what kind of operation system to use, DOS, P-DOS, Xenix, or some multi-
   user shell like MultiBase?

3. what kind of multiport to use, Digi-Board or other RS-232 board?

4. what kind of database to use, for multiuser do I have to load database
   program several times or just load one copy? how hard to program for
   multiuser database? are there good books for programming multiuser
   database?

5. Can terminal and printer together share one cable connecting to a
   RS-232 port on the computer.

Thanks in advance.
