U205 is the CPU that controls the MIDI stuff, U207 is its program ROM and U211 its RAM.
U208 is the chip that actually makes the sound, U212 is the sample ROM but U204 I'm not totally sure what it is, possibly some memory or effects related thing if the thing has reverb capability.

Thanks very much. Would it be correct to say that its wavetable ROM is called QSonic MX? If so, have you ever come across this "brand" of wavetable ROM before?

PS. Something's wrong with the image you embedded, it won't display over here...

The image displayed when I was first replying, it doesn't anymore.

The ROMs are manufactured by Macronix for Qsonic, the big MX is their logo. Yamaha things for example have ROMs made by Fujitsu, Macronix, Mitsubishi and others, it is a very common practice.

To know the size one needs to count up the address lines used. It most probably is not going to be larger than 2MB.

Thanks a lot for the info! And thanks a lot for the heads-up about the photo. I'm a bit puzzled by the photo problem. I wonder if I'm doing it wrong. I put my photos on google photos on the net. For the photo I want to use, I use the "Copy Image Location" mouse right-click functionality. Then, using this long URL copied in to my clipboard, I paste it between the IMG tags for a Vogons post. It works OK for me, but then it can't be working correctly, because you can't see the image (now). (I wonder why it could be seen initially, but now it's gone?!) Is using the "Copy Image Location" mouse right-click functionality bad practice, and unreliable? Perhaps I need to display my images using a better technique? Thanks for any insight in to this matter!

Edit: I have changed the photo in the original post, to see if that helps, but I'm still puzzled by why I had the problem in the first place. End Edit.

You can upload pictures directly to the forum now and place them inline so they show up. They just have to be 2MB or smaller in size to do so. Easy enough to resize them with GIMP.

Yeah, that's never going to work.

In my experience the "Copy Image Location" link you'll receive from Google Photos is only temporary at best, depending on how you're sharing the photo. If it's not in a shared album and you have not clicked the "Share" icon to get a link to share, you will likely not have a stable URL that others can use, only a URL that you personally can see in your browsing session.

If you really want to host images on Google Photos and share them in forums, try this:
1. Click the "Share" icon above the photo you want to share.
2. Click "Get Link" and copy the link you receive.
3. Copy the link into here: https://www.labnol.org/embed/google/photos/ and click "Generate Code"
4. Copy the "Direct Link (URL)" link.
5. Paste the URL in your new post here and enclose it in Img tags.

That... might work.

Otherwise as was said, you can upload photos as attachments on VOGONS, or use Imgur and the like (not Photobucket).

Thanks for that great info! 😀 I've just tried this. Do you see the image in my original post?

Picture is showing up fine now.

Working fine here! I wasn't sure how well that process would work, but it seems to. I'll check on this months from now to see if it still works.
