General Questions (actually specific ones about OPL and SID parts)

[napierzaza]

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...

[napierzaza]

Oh, anything Montreal,Quebec,Canada specific would be appreciated (or Ontario too).

[napierzaza]

Though no one seems interested I've identfied the chip as a YMF704c-s which is the generation after the the desired one, anyhow I suppose that's useless at least.

I had a look for a datasheet for a YAC516, but i can't seem to find one online.  The Yamaha DACs are specific to the synth chip, so anything other than a YAC512 would need a circuit redesign at least.

Have you tried your local second hand computer stores?

[napierzaza]

Would they really have those sorts of things? It was my assumption that no one would sell those sorts of things anymore.

I believe this is the datasheet:

They might do, you'd have to ask.  It may be time to resort to eBay or similar.  Check the wiki page to see which cards are known to have the OPL3 chips.

[napierzaza]

Who do you mean I should ask?

[fluke]

The second hand computer stores.  They're bound to be getting people trading in PCs with ISA sound cards on them.  They may not be keeping them though.

[napierzaza]

Okay cool,

Actually partial success. I actually found a computer in the garbage with an ISA sound card, not the right kind, I think it was a crystall chip or something. Another boon is that I asked a co-worker and he said he has some and will bring them in (nice).

Thanks for the help BTW, I'm still fairly unsure about how to go about this project!

Hi,

you have seen the Wiki page (fluke already said it) listing all the soundcards with the OPL-chip on it, have you?

You could set up an ebay alert search. This way I got two ISA cards for 4,50 EUR each. Just be patient and let the parts find to you ;)

regards,

Michael

I didn't see that page (thanks) but I saw another one. The ISA card I got was in the garbage so it's not a monetary loss or anything. I'll not so much be checking out the card name when the coworker brings them either, just loking for the chips.
