Hope you can put them to good use 😃👍🏻
Re: What retro activity did you get up to today?

Got a retro YMF704 soundchip and built an Eurorack Module for my synthesizer around it. Best of both worlds 👌🏻😃👆🏻 https://youtu.be/id5fTAAdnRg

MHS chip, you mean the AY-3-8910? I have bought some replacements for this chip, the YM2149.

Send me your address over PM? I have put the chips in an anti static box and that weighs about 35 grams, so add the envelope to that and it still will be less than 100 grams.

Hi All, Maybe I can make someone happy with an original 1978 processor? I found in my old stack two processors and you can get them for free, just pay the post costs. They are an Intel '78 8086-2 and an Intel '78 P8088. Just let me know...processors.jpg Also found an AY-3-9810 sound chip. Also for …

Sure, my hobby is working on a modular synthesizer, design and build most modules by myself (and sometimes I get help from a forum member…) I have made several modules around the YMF262, and I think they sound great. https://youtu.be/-cAcPInczns But I bought an YMF704 and I’d like to build a module …

I discovered why the volume was so low and distorted... It was all because I made a mistake. Looking at the datasheet of the YAC513 I thought to notice that this chip can be used by an YMF721, but it said YMF271.... My mistake, the YMF721 needs an YAC516. So I orderen some and the coming weeks I …

Thanks! I just got in touch with Tiido, and he proved to be of great help. The chip is making sounds, albeid at a very low volume and I can only hear a piano sound (not using the FM part at the moment). So I’m trying to figure out how to increase the volume and change instruments.

Hi, I’m trying to wire up an YMF704C but the documentation is very hard if not impossible to come by, others than the very limited datasheet. Is there someone out here who can send me a circuit diagram how to hook up this chip? I have some expertise in using the YMF262 (hard and software) but now …

Thank you for your kind offer! And sorry for the high pitched notes, I have tinnitus so it's not effecting me ;) The first demo I filmed I used a three ops version and not really polyphonic, but the latest version is 4 ops, 6 voice polyphonic. Took a lot of figuring out and also a lot of help from …
