Well every day's a school day! Does this mean that cards that use the
8X300 chips could be updated to more modern hardware? Is it possible
that MSCP code could already more-or-less exist for the PIC
architecture?
Doubtful, as it's just the same architecture, and far from the
same implementation. The 8X30x chips are bipolar, if memory serves.
But either way, I'm not sure what the point would be, aside from
possibly building new boards using an existing 8X30x MSCP
implementation.

PIC as is Arizona Microchip PIC, or PIC as in
something else?
The very same. The architecture made its debut in the 1970s with
the SMS (later Signetics) 8X300, which many of us have seen on disk
controller boards.
Here's a snippet of a classiccmp post of mine from back in 2001:
------------
GI adapted the SMS/Signetics 8x300 for use as a peripheral
interface
controller (PIC) to augment the poor I/O of its CP1600 processor.
GI's
IC division was spun off to form Arizona Microchip Technology (sound
familiar?) in the mid 80's, producing EPROMs, EEPROMs, and..."PIC"
processors.
