Maybe Turtle Beach 56K line (Pinnacle or older Multisound) ?
Interesting, but i dont have any of those and prices seems to be too high. Theese cards operate in a different matter than other ISA Cards since you mention them?
Another thing i found about the Winbond W83626F bridge chip is that it doesnt support ISA busmaster. Do soundcards use that?
Turtle Beach Multisound series feature a very high audio quality, and they don't use DMA. But it's not guaranteed they will run on your system. That said, they are very tricky to setup, especially in newer systems. I for one couldn't run a Turtle Beach Pinnacle on a Pentium 4 Windows 98 SE system no matter how hard I tried - there always were some resource conflicts.
If you manage to avoid or solve these conflicts, you will get sound and MIDI in Win98 (Tahiti and Fiji will give sound only as they have no MIDI synths). But concerning DOS, the situation is less bright:
- Multisound Classic will give you sound and MIDI, but with just few games out of the box. Some tinkering with the drivers will give you maybe 100-200 game titles. And you need a MIDI driver patched by me, otherwise you'll get mismatched drums.
- Tahiti is like Multisound Classic but with no MIDI engine. You will get PCM sound in maybe 100 titles if you tinker with drivers.
- Pinnacle will give you a quality MPU-401 MIDI that is compatible with nearly everything, but no sound as Pinnacle's PCM engine has no drivers for DOS games.
- Fiji will give you nothing as it's just a Pinnacle without its MIDI engine.
Also have in mind that TB cards are somewhat rare and expensive, and usually you have to pay about $100 for one.
So, let's sum up:
Strengths of TB Multisound soundcards:
- very good quality low noise output
- high quality MIDI engine (in Classic and Pinnacle)
- no DMA needed (although it's not anyway guaranteed that they will work with your motherboard)
- resource hogs, high probability of conflicts especially on later systems
- hard to set up
- incompatible with SB and Adlib standards
- not so much DOS games support Multisound Classic PCM audio - only titles that use DIGPAK sound library
- really fucked up DOS support of Multisound Classic's MIDI engine: both patch loader and AIL driver work incorrect. I kind of fixed the AIL driver (minor inconsistencies still remain), but not the patch loader, and to get patches loaded correctly one needs to run Windows 3.1, wait for its drivers to load patches into the soundcard, then exit Windows 3.1, and only then you are ready to go.
- no DOS PCM audio support for Pinnacle and Fiji
- hard to get and expensive
Imho, if you like to spend 100+$ for the sake of experiment, you might buy a Multisound Classic to see if it works with your system. But anyway you won't get many DOS game titles working even if you succeed. If you just want to play games, you better turn away from TB Multisound series.
Although, if you're aimed primarily at Windows gaming, then your chances are substantially higher.
Myself, I have both Classic and Pinnacle. Currently I use Classic in a Pentium-60 Socket 4 system with DOS and Win 3.1 (as it is currently impossible to use the card without Win 3.1).
