The UNIX that is available on the PC 6300 PLUS is truly a multi-user
system.  The machine is supplied with a serial port, so an external
terminal can be used in addition to the system console. 
The Hardware Reference Manual and Integrated Software Development
Guide have the necessary information for developing a serial card and
UNIX driver.  Four and eight-port cards and a driver are available
from CTC Systems, Inc, 10311 S. DeAnza Blvd, Cupertino, CA (408)725-0501.

Of course, performance depends on the system load.  More expensive 
systems can handle more users;  however, the PLUS should be
satisfactory for many applications with two, three, or more users.
