Gunther,

Great explanation of the token system!  Almost makes me want to write my own for my SX projects, but I enjoy writing in SASM too much.

A quick clarification on the EEPROM:  you can write to most EEPROM any size data you want, you will just have to wait for the internal write cycle if you change pages.  EEPROM is eminently usable with the SX.  In most applications that I have written, I have been able to have the SX do something else while waiting for the EEPROM to do its internal write routine.

Also, the SX program registers are 12 bits wide (not 14), so you can store 1.5 bytes of hardcoded data in each program memory location.  I have written a driver application that runs a 640x480 LCD using a tile (sprite) system using the program memory of the SX to store alpha-numeric and other characters.  Since you will probably be writing to the memory with IC2 or some other serial system, the width of the program memory registers is irrelevant as long as it is known.

My $.02
