	STA  ENAM0              ; Clear a bunch of registers.
	STA  ENAM1
	STA  GRP0
	STA  GRP1
	STA  GRP0               ; In case GRP0 isn't COMPLETELY zeroed.

That last instruction is needed because VDELP1 might still be set, so
another write (of anything) to GRP0 is needed to make sure the zero
in GRP1 is displayed.  (So I guess the comment should read "In
case GRP*1* isn't completely zeroed." :) )
