	; The following routine is based on reading the public KERNAL jumptable routine
	; list, and making unimaginative assumptions about what should be done on reset.
	; Initialising IO is obviously required.  also indicated by c64 prg p269.

	; also affirmed by p269 of c64 prg
	jsr ramtas
	; Resetting IO vectors is obviously required, if we want interrupts to run
