I have a few older soundcards in my old game machines (still in use)
These include:
Gravis Ultrasound Max ISA (upgraded from .5 to 1mb, had to kill a video card
for the ram)
Gravis Ultrasound PnP ISA (with 8mb ram)
Soundblaster 16 PnP ISA (with a Yamaha dbx50 midi addon card)
Soundscape ISA (the original long card resold by reveal)
Soundscape PnP ISA (used in gateway machines)
Soundblaster Pro 2.0 ISA
The soundscapes are not in use at the moment, have the SB 2 pro and
Ultrasound Max in my 386/40 game rig and the SB 16 dbx50 Gravis PnP are in
my p200mmx game rig. Its a pain configuring multiple soundcards in one
machine but once its setup it makes retro gaming fun and 100% compatible.
A pair of Sounblaster 64's (one is in my server and other answers my phone)
And a handfull of the Aureal sq2500 chipped PCI soundcards
Still havnt found anything for a nubus mac that doesnt cost alot just to
tinker around.
I have a few older video cards as well.
