They might be thinking of the Sound Blaster Pro or Pro 2 which were 16-bit ISA cards, although really they were basically still 8-bit ISA cards that only used the extra pins on the 16-bit connector to give you a few more choices for IRQ/DMA. My gut feel is that the Pro and Pro 2 were when the SB really hit the mainstream. A lot of people I knew had them at the time, at any rate.
