Currently working on restoring a Pentium 70 class NEC I found at an estate sale. Looking to give it a Sound Blaster of some kind. Seemed like the cheapest easiest way to go was a simple SB16 PCI since it has PCI slots, but the system requirements of those cards seem to indicate that a 133mhz Pentium or faster is required and windows 98SE. Would it really not work on something slightly older? The ISA SB16 cards seem to support older hardware?
