EEPROM Memory Map
; -----------------------------------------------------------------------------
; Look-up tables......
;
; First we check out EEPROM. If the checksum computes transfer it to RAM.
; If checksum incorrect then get data from ROM.....
;
; EEPROM B600-B63E (checksum at B63F) - This is where Dataset 'A' lives
; B640-B67E (checksum at B67F) - Dataset 'B'
; B680-B6BE (checksum at B6BF) - Dataset 'C'
;
; RAM 0080-00B5 - modifiers are here
; ROM F740-F775 - get from here if bad EEPROM
