ahh man you just reminded me. the cd-roms on those machines didn't have the silly audio cable that pcs of the time did, rather they were just connected via scsi. playing audio cds would rip the redbook cd audio stream in real-time and transfer it over the scsi bus where the host would reconstruct the pcm and write it to the dac.

i liked the aesthetics of those machines and the tactile feel of the keyboard.
