Hey also curious. You mentioned you had a "little box" for that Sound Accelerator II board. What does that look like? I've seen the Black and Beige small metal boxes that hook up with DB-25 cabling to the back of those cards. They had the analog one and a digital IO one, but they were both basically 1/2 rack width metal cases... Then they made the "pro" 1U rack unit with all the spiffy lights and both analog and digital io in one unit.

ooooh the power of 1989!
