; You will find MANY sections here unaccounted for,
; I would like some day to have a complete version,
; just like the famous "The Complete Spectrum Rom Disassembly"
;
; Some information was obtained from Peter Gerrard's and Kevin Bergin's
; book "The Complete COMMODORE 16 ROM Disassembly" available from
; Duckworth - ISBN 0 7156 2004 5
;
;
; Much of this will not compile due to the "extra" opcodes
; that most assemblers will not recognise. where possible
; I will include DB's or DW's
;
