Why do people insist on calling them 720 K disks? There is no such stupid
invention. They're 1 MB disks, not 720 K, not 800 K, not 880 K.
Oh, and there are no 1.44 MB disks either.

Amiga shops should be able to supply them. But they haven't been easy to find
for the last five years or so. MicroWarehouse still features them in their
catalogue, though at a premium.

OTOH, Macs with SuperDrives should do it.

En ligne avec Thor 2.6a.
When cherry tree blooms, people go and walk there, eat dumpling, bring sake
and talk each other such things as "A superb view!" and "Full of spring here",
and they become very happily and cheerful. But this is a lie. People gather
below cherry trees and get drunk, vomit, fight, which are happening since the
old days of Edo period. From long time ago.
