Sweet machine. I know the later chips
are programmable, but the
53C90B is a very old design, and I didn't think the built-in processor
was introduced that early.
Correct. The 53c9xy chips had a fixed-function, state-machine based
architecture. The SCRIPTS processor was, as I recall, introduced with
the 53c700 and improved in the 53c810 line. Nifty stuff, if you're into
that sort of thing.
