Hello,

I was wondering if anyone has a DIY circuit schematic that I could build around a ZIF socket to test SID 6581 chips. I don't have a Commodore computer but would like to test the chips I have for basic functionality.

Thanks.

What are you going to drive its address and data bus with? What test equipment do you have to check its output?

You'd also need a clock source. Probably something in the 500 KHz - 1.2 MHz range would do.

IIRC you can get away with only using the +5 Volts power source but the filters won't work.

Getting a C64 would be less expensive. There are several programs for SID testing that will help you.

OK, that's probably not a bad idea.

Would you recommend de-soldering the SID chip in the C64 and replacing it with a ZIF socket or perhaps building something that would use the cartridge port instead?

SID is usually socketed anyway. You could replace the regular socked with a ZIF one for the sake of convenience but I wouldn't bother unless we're talking a REALLY significant number of chips to test.
