This is one of my favorite photos of the card: http://yehar.com/blog/wp-content/uploads/2010 … CT2940-cut1.jpg 🤣

Good luck with this.

Here's an old VOGONS thread with some info that may be relevant. The last post has a link to a CT2940 w/CQM pic:

Creative CT2890 PnP vs CT2940 (Sound Blaster 16 models)

Here's a post from dave343 with pics from a CT2940 w/OPL3:

Whats the best version of the Sound Blaster 16?

And just in case, here's a CT2900 pic I found some time ago:

As for your proposed transplant, I second what firage said - good luck, you will definitely need it.

Ooohh, the pain......

It is interesting that crystal X3 is used in the CT2900 but not for the CT2940.

X3 is used on my CT-2940, which has an Yamaha YMF-289 OPL3-L and YAC-516 DAC.

Hmmm odd, might be optional but is definitely for the OPL3/DAC

It's not optional if the Yamaha chipset is present. It was already determined that the crystal had broken off of the card in that photo.

I think I actually found a CT2940 recently at a local computer recycling center. Should still be there, nobody looks for these retro parts here. I have no idea whether it came with the OPL3 or not, I lack pictures of that card when I was taking them for certain parts to look up later as my camera was almost out of power. I should take another peek at it again.

Alas, said place is not open until Monday. Would be a bummer too if it doesn't have the OPL3 chip.

Edit: Actually, looks like I did have a partial picture of it, just the left side though. From the design of the PCB and using the power of Google, it looks like it's one without the OPL chip. 😒

Yep, it's as I thought it was going to be. Uses CQM instead of OPL3.

I thought the same, and I got the half that contains the OPL chip!

Another high-res photo:

You can see the CT1978 integrated chip with the CQM (above the CT2502) and the placeholder for the OPL chip (to the left of the CT2502).
