Control-G Does not produce any noise on the 64. There are no sound routines (except to clear the SID registers at start-up) in the 64 ROMs (I think they were rushed on putting the 64 to market; later they released Super Expander and Simon's BASIC which offered sound commands.) I usually use a game cartridge to check the 64's sound, video and joystick ports. Jumpman Junior seems to be my favored one (mainly because it does not rely on much of the KERNAL/BASIC ROMs in it's operation.) And yes, the Genesis A/V cable is compatible with the 64 (I've used the same cable on both units). -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-
