I'm sure there's ones to NOT get like an ESS based one, but i'm pretty sure you'll be in good shape with almost any 16 bit isa card in DOS.
Rampy - the 2 ISA sound cards I've dealt with were both ESS and I didn't have any probs with Mame. Is there something about ESS that I should be staying away from?
Just annecdotal, from back in the day... i think ESS chipset had a perception of being noisey, cheezy, not as good drivers support (but that might have been windows drivers) but it might be just earlier revisions of the chipset... but it seemed that computers back then that used it either embedded in mobo or as a card, like compaqs had them and they always seemed to be a pain... so its more a perception on my part than actual fact.
If ESS chipset card is working for you, than cool.
I just wanted to give some sort of recommendation, like using sb16... because it can suck if you get a bargain bin, flea market isa and can't find drivers, etc...
I dunno.. I guess I'm just rambling... vague not fully formed ideas...
