For a particular box to have a security hole is one thing. But for the
processor to have a security hole etched in silicon means that there is
no security ever possible.
I have had the idea of a switch to real mode in ring 0 suggested,
and that sounds kind of interesting.
Would anyone use a 286A if it came out?

Uh huh. And what about the 386SX he mentioned as being so superior
for running Word for Windows?

|And DESQview without a 386 is like Unix without bg. How many of us have
|EEMS boards?
A 386 makes DESQview much easier to run, but so do the All Charge Card,
the SOTA Pop, and several other products which are under development.
As a matter of fact, a lot of us in my group have AST Premium 286s,
with EEMS.
But if multi-tasking were so important, I would think QuarterDeck
would be almost as big as Microsoft. I don't think they are. A lot
of people's reaction is "why do I need multi-tasking?" I don't
understand it, but there it is.
