Do you know
which ones used QuickDisks? The ones I have or have seen
use 3.5 inch disks.
(Fibber Magee goes to his closet)
I've got a PWP-5G portable here that uses them, and my notes say that
the PWP-1000, 2000, 90 and 3 used them also. Other than the 5G in my
hot little hands, the list is by no means complete nor authoritative.
