The PC had no effect. A 2400' reel held 180,000,000 bytes, minus inter-record gaps. Putting that many data on floppies is not an attractive option. Even a small DTR represents a lot of floppies.
Now, when you started having R/W CD, DVD and flash drives, that changed things. Of course, by then 9 track 6250 was considered to be the oldest type of tape that still existed. -- Shmuel (Seymour J.)

Sometimes it was on cards, sometimes on those small diameter tape reels IBM sent service on, sometime listings, sometimes microfiche. When PCs came into the picture, I assume it got much easier. And now I assume security has made it much more difficult. Gary On 2020-08-05 8:23 a.m., Seymour J Metz wrote: > I suspect that's most of us. > > > -- > Shmuel (Seymour J.)
