There is a card out, the manufacture and name escapes me, but it was
something like Above Card, that uses one PC slot and is a seperate 386
processor, RAM and ROM (ie a computer with no I/O.).  The does not
depend on the microprocessor of the machine it is in, in fact, it allows
true dual processing. (not co-processing, but dual processing.)  Both
micro processors run like they are stand alone computers and you can
have different programs runnning in each.  The output is controlled by
what ever processor has the screen.  I am not sure of the specifics, but
I think it i/o is interrupt driven.

The card sounds like a good idea, but it is not a new one.  The Xerox
16/8 was actually similar to this except the main board was a z80 based
computer and the dual-processor was an 8086.
