I have somehow blown my sound chip. The machine seems to work fine for most programs this is no problem. But there are a few of the games which my children enjoy that just won't work. I have opened the keyboard only to find that all of the chips are soldered in place. (I am not very adept at this hardware type stuff.) I am looking for an economical method of fixxing it. All of the estimates that I have gotten to fix it have been so high that it would be just as cheap to buy a new C64. PLEASE HELP!!!!!!!!!!!!!

You can probably purchase a new SID chip from a commodore repair shop for about $15 (I may be off by a couple of dollars about that). Just be careful not to apply too much heat to the new chip when you solder it in. Another way to go, may be to solder a socket in place of the old chip, and plug the new SID chip into the socket, that way if the chip burns out again, you can simply plug another one in!! Vic Sohal

If you are unable to find local help I know of a repair person whom I can *highly* recommend that will handle repairs via UPS. Please excuse this commercialism: $35 is the flat rate for labor and shipping. Major parts are extra. A sound chip is $15. You must: 1> Send via UPS. Preferably insured, but UPS only pays "blue book" values for damage or loss. 2> Include your power supply so it can be checked for subtle problems as well. 3> Include your Phone (with times), name and address INSIDE the box. 4> Include payment or means for payment. It is probably best to call first.

That is the usual cause of a silent-but-still- working 64.
