You have it right Casey. The Xcat emulates the 2K x 8 EEPROM. The
same concept could be used for the X9000, but of course the EEPROM
contents should have to be fully understood or at least the contents
we need to modify. The giants had already figured out the original
X's layout before I got involved. Getting the timing right was a
challenge, but that was with a 20Mhz PIC. With a 270 Mhz dual core
ESP32 it might be a little easier.

My thought is to take out the EEPROM entirely and present a dynamically changing equivalent of it to the uP in sync with its EEPROM read requests. I believe this is what the XCAT does.
