Well, it is hardly fair to compare Uport's 286 compiler with AT&T's 3B2
offerings, or with ANYONE's offerings on the 386.

It is my understanding that System V/AT (including the C compiler, which
is AT&T's PCC) is a port done by ISC and Intel for AT&T, and that AT&T
certified it. Uport supposedly only added the drivers, just like for
their 386 product.

What I would be interested to know -- and am surprised that we don't hear more
from them -- is what people's experiences are like with AT&T's PC6300 Plus,
with UNIX -- this is a binary-compatible implementation of UNIX for AT&T's
286 machine, presumably derived from the same ISC/Intel port as Uport's
System V/AT.

What problems are there with it? With its floating point implementation?
With it's compiler? With its disk drivers and serial port drivers?

THAT would be comparing apples with apples!
