What sort of hardware would have been used for hard disk recording in the '90s?

[flux capacitor]

Back in the (mid to late) 1990s I was working as an intern in a small recording studio. They had an early digital recording setup with a Yamaha console (an O2R, IIRC) and Pro Tools running on a Mac (might have been a PPC, but I think it was a 68k one).

Over the years I've often been asking myself, what exact hardware they might have been using, and if it would be possible to re-create that setup today.

Does anyone have a good guess, as to what kind of DSP cards were around back then, and what would have been a typical setup capable of recording multiple tracks (must have been at least 8, if not 16) at once?

digidesign pretty much had processing cards for nubus, and also i'm pretty sure some form of nubus cards (but I don't recall now if that was digidesign or someone else instead) had spdif and/or aes3 in some way too

Butch Vig has had interviews throughout the years where he talks about the hardware he has used in productions and in his own studio. He’ll get pretty nerdy with it and specify exact hardware/software/computers involved.

(The liner notes for the Garbage album Version 2.0 even mention the specific Mac they used - Power Mac 9500/200)
