Awhile back I picked up this 2230 becasue it is a semi desirable card, just 1 problem it's only semi desirable because it has a noisy DAC. No problemo.

Step 1 desolder both dacs with hot air.
step 2 solder on the good dac on the sb16.
step 3 clean the card so its "LIKE NEW"
Step 4 now we have a desirable card.

That's definitely a worthwhile swap to do ~

Destroying an ISA AWE64 card to improve a SB16 is extremely stupid.

I donno, maybe they value having legit OPL3 and a wavetable header over AWE capabilities.

What is known about these DACs? For instance, are these Creative-marked ICs variants of other industry-standard parts, or do they have common pin assignments, so that one can just choose an off-the-shelf part for the replacement? One of these years, I may again want to play with a Creative card, but memories of the noise levels, among other things, often cause me to abandon the idea. It also seems somewhat wasteful to have to buy two Creative cards just to get one somewhat quiet one.

I must be stupid, too then, because I thought about improving a SB16 CT1740 once. ;)
These 'Noise Blaster' are usually not held in high regards, but I value their jumper-based configuration a lot.

He can always solder the DAC from the CT2230 onto the AWE64 and still have a fully working card, albeit a bit more noisier 😊.

I only know that the codec chip is remarked version of some Asahi Kasei stuff, but what exactly I am unsure. The pinout seems to mostly match the chip found on Yamaha DB60XG for example (which is also very noisy).

😀 not really a waste if you think about it. The features of a 2230 make it a superior card to a awe64 value in a few ways. Real opl3 vs atrocious cqm. Wavetable header. Not pnp. Also it doesn’t have bugs just like the aw64. Plus this make it low noise like the awe and the aw64 was a parts card I didn’t buy it and I only paid 25 + free ship for sb16

Did someone one mention leveraging DACs out of one of a billion dead CDROM drives or audio players once or did I imagine it?

There are plenty of SB16 clones and none of AWE card around. With or without "real" OPL3. Why? Because AWE is superior and is hard to be cloned. One have to clone a whole e-mu CPU/SP. The wavetable header connector is equal to a DB15F MIDI connector 😉 Unless you insist on plugging your joystick to your SB card instead of to a gazillion gameport cards. Jumers, vs. PNP, well you have at least three ways/programs to configure you card even on a 286 PCs! Just learn them! What you payed for the AWE card is completely irrelevant and is apart from all dependable on seller's knowledge. What are you boasting yourself for? For your soldering "skills"? Ridiculous.

Lol,

Whatever people want to do with their own hardware is their own business. I'd be throwing stones in glass houses if I started ripping into people for trying to improve/repair their hardware. I'd be certainly disappointed if people were deliberately trashing rare hardware for no good reason, but I'd have no recourse against it in any case.

But the AWE64 Value is not rare. It is hardly even noteworthy. Neither is the CT2230 for that manner. Both are common cards.

I'll have to check my CT2230 (or was it CT2290, I can't remember) card and see what DAC it has on it. It seemed pretty good as it was though.

Owing something doesn't mean you can design or make it 😉 People own land but does this mean it is good to destroy/devastate it ? Or is it their own at all (maybe it belongs to Nature!). Destroying a no longer produced vintage card is stupid. It is common now but will it be common tomorrow?

I wouldn't say I actually "like" the AWE series, but the EMU8000 was a fine and interesting chip.
I'd love to see it being "freed" from those lower end AWE cards and being turned into a "Goldfinch" clone card with good shielding ang galvanic insulation, maybe spdif out, too. ^^

I don't think we truly ever own the land, merely lease it for life... property taxes I guess, life-lease, like we don't really own the sound cards because we don't own the patents or designs behind it to recreate it or adapt it. ownership is a farce

Calm down, you'll get the pro-youtubers excited about engagement potential, hater views are still views, and then we'll have Will It Blend:- Vintage Hardware Edition.

Land is a different class of ownership than most other products though. Even so, you have a lot more leeway with what you can do on your land vs what you can do on public or other people's private land.

That said, for items like sound cards and computers in general, people are allowed to change/modify/destroy it in any manner they see fit. It is really a YOU problem if you feel that you need to control what other people do with the general property they own.
