Well, I am asking in general, since I may want to do it on many vintage PCs that I am going to get soon. Also, it is fun to just explore what new software and hardware the super enthusiasts have developed. (Wish I could find that spare CF card adaptor board, come to think of it.)
The exact computers that I am going to try these drivers on right now are a Swan 286/12 MHz. and a KLH, also 286/12 MHz. The Swan is a medium beige metal box (vertical expansion slots, but not a full-size box) and the KLH is a small beige metal box (3 horizontal expansion slots). Both easily have a free slot. Once I find that spare CF card adaptor board, I think I will add it to one of them.
Yes, actual sound cards are an option. Those can get expensive, though I do plan on eventually getting them.
