Okay, I'm interested in the two synthesizers, the OPL and the SID. Aside from getting enough money for the kits themselves (eep), I'm having a deal of a time looking for the main chips! Is there anywhere where I can buy them for a reasonable price? It seems like there just isn't anyone who wants to sell a c64 near me, not to mention no ISA cards. Also, I DO have a soundblaster card with some chips on it. Can anyone tell me if the YAC516-E works the same way as the other DAC? There's a OPL chip with a lot of pins on it which I assume doesn't work as the main chip, but I was wondering about the DAC...
