I need to upgrade the cpu in a system to get more memory, speed and
any other features that might be availble. The replacement cpu needs
to be pin compatible with the 80c51fa. I'm leaning toward the Dallas
89c450. It has 64k of internal flash code memory, 1k of extra RAM,
and runs at 1 cycle per instruction (x12). The crystal that I'm
currently running is only 11 mhz. Would that be the best chioce for
memory, speed, availability?

thanks,
Wilfred
