I will modestly refrain from boasting about the PC6300 PLUS or
Simul-Task, and confine myself to a few technical comments.
	Simul-Task supports only one MS-DOS task, and only at the 
console.  These restrictions will be lifted in 1987.  (Of course,
any standard DOS software like DesqView or Windows will work,
so it is possible to get that kind of DOS "multitasking.")
	I am not familiar with the Opus board, but in general
one processor running DOS and another running UNIX will perform better
than one running both.  Compatibility and integration are another matter...
	UNIX on the PC6300 PLUS comes with the uugetty command.
uugetty has a "-r" option for the specific purpose of having
two systems directly connected with getty's running "nose-to-nose."
If you set up your PLUS from the UNIX Office so that the relevant
RS232 port is "BOTH HOST AND CALLER," it will set up a "uugetty -r"
on that port for you.  The port can be the built-in or one on 
a CTC serial expansion card.  If your Zilog has uugetty, you're
all set; if not, perhaps you can put up Honey-DanBer on it.
