Hi! I just broke one of the pins off of the YM3812 chip in a piano I was modifying. This forum seemed to come up a lot when I was googling around, so I figured I'd ask you guys if you had a adlib or old soundblaster card that had the chip on it, as I'd love to buy it if you want to get rid of it.
😳 There's not even enough of a nub left on the pin to solder a wire to it?
Yeah, the pin is flush with the side of the package. 🙁
I'm gonna try drilling into the package to expose the lead, seeing as how that's my only other option.
That should work as long as it's in a plastic package and not a ceramic one.
Got any advice on doing such a thing? I'm real leery about messing it up, considering this is the last chance I've got for it. I have a dremel too, if that's a better tool.
why not search eBay for a Soundblaster 1.0 or 2.0 ??? those have the 3812 chips you need 😀
like that one: http://cgi.ebay.com/Sound-Blaster-8-Bit-PC-XT … id=p3286.c0.m14
although it is a shame to kill a 8bit isa sb ...
OR
just get a 3812 for 25$

$25 is ridiculous when you can buy a whole sound card for less than $10, and the chips in those are often socketed so you could always put them back in.
Gah, so I jumped in and drilled out the pin, but the chip still behaves oddly. It's on this old Yamaha electric piano, and it makes sound, but the pitches are all wonky, and I'm not one for microtonal music...
So I guess it's safe to assume that noone has a card they can part with, for like $10 bucks or so, even?
Problem solved, hopefully. I convinced the $25 chip guy to sell it to me for $10. Still kinda steep, but I needed the chip fast. Thanks for the links and advice too!
