   The Data General One is ALMOST compatible with the IBM.  A MAJOR
difference is the serial ports. The DG/1 uses 8251 serail chips instead
of the 8250 (I guess no cmos 8250's?).  At any rate, no standard PC
terminal program will work.  I would like to get KERMIT up on the DG/1.
This requires knowing how the 8251's are connected to the interrupt
controller, etc.  DG apparently hasn't released the tech manual yet.

	Help! Does anyone know how to use the DG/1's serial ports
in interrupt mode?  Has anyone seen the tech manual?
