I used a Sound Blaster AWE64 ISA on my RDD, it has Windows XP and worked fine.

Unfortunately I had to replace it with an Ensoniq AudioPCI first and a SB Live! then because the Asus TUV4X has no ISA slots, or else I'd still use it.

I understand it may not have positional audio or anything like that, but would normal stereo support it in 1999/2000 games ?

SB16 can output only 44kHz. Sound quality in later games may vary.

The lower number of sounds that can be played simultaneously may become rather apparent in some games.

And can exhist a “modern” isa card to use with win98/winxp?

YMF719 is great for both DOS and Windows. AWE64 is OK, but only really interesting with the ram expansion.

I'd say ISA card is more or less comparable with onboard AC97 sound chips in XP. Nothing fancy but it'll do the job of making sound just fine.
You have the benefit that XP includes the drivers so you can listen to the install music as well 😉

Win98 isa is fine, in fact both cards kolderman mention above only really start to get fully utilised in windows

but the difference in cost between the two cards is enormous ...

YMF719 also has 48kHz option.

SB Live,Audigy, and even X-Fi cards are very inexpensive. If you are using a Pentium 3, having hardware accelerated audio could give you improved performance in games. That's not even including the higher quality audio you'll get.

Yes, a SB16 should work, but there are many other options that can give you a better experience that are inexpensive.

I not have a PCI SLOT, only ISA.

which one?

YMF719 more expensive? There's one on eBay for EUR 13.49 Buy It Now...

Apart from that, any other card that supports WSS (and so 48kHz) should be fine too. There are lots of options, which is best depends on exactly what you want.

I mean that the price difference between the ymf719 and the awe64 is huge, not that the ymf719 costs is huge.

I don't know exactly what requirements an isa card that works well on windowsXP should have, I don't know which games I will try on this card, I would need to know if they exist and what models they are. I mean a card that can use stereo sound from games up to the 2000s (target games of a 1.0Ghz PIII cpu).

Can you share a photo of this s370 board with only ISA slots please?

it is an SBC installed in a only ISA backplain

The only requirement is you can find XP drivers.
If the card supported stereo and they have bothered to write an XP driver it'll support stereo as well.

To keep the list short I'd look for
SB16/Vibra 16. Native XP support but nothing special
AWE32/64, Basically a SB16 but you can mess around with sound fonts for Midi playback
YMF card, Gives you XG Midi

Now I want to see it even more 😀

the most advanced isa card is the one with yamaha chip?

In terms of raw sound, yes.
In terms of hardware MIDI capabilities, it's the AWE32/64.

I would not say advanced, but it has genuine OPL, pretty good soft synth that works with DOS games in Win98, bug free midi, clean digital sound, works well for Windows apps, just a good all-round card.
