I don't know - the earliest Avid products I worked with were from the late 1980s and
early 1990s and used digitized video with the largest hard drive and biggest RAM that I
had worked with up to that point. The MCR video playout system that I worked with stored
all the short-form video in a bank of SCSI drives, and we ran all of the long-form
manually from a bank of U-matic decks or directly from sat - all of the switching done
with a Grass Valley switcher run by the Avid. We did all of the long-form preroll with a
built-in preroll cueing function in the U-matics, and rolled them by hand, IIRC correctly
(that was about 20 years ago).
