I spent $25 on a bit of nostalgia and will confuse the heck out of some youngsters today.

Thatโs right. But if you were lucky enough to have an AdLib sound card back in the day, you could avoid IRQ hell altogether that often came with having a sound card and a modem in the same box. The AdLib didnโt require an IRQ at all. I was not so lucky (my dad was, though), so getting my modem and sound card to play nicely in a new build was always a day of jumper-swapping. Some things certainly are better now.
I truly do not miss IRQ shenanigans.
