I'd say yes indeedy the 720kb disks can be formatted to the Miggy's 880kb. Any relatively modern 3.5 disk that is double sided-double density has worked. I've also heard that 1.44mb disks dumbed down to 880kb can be unstable, but out of the thousands of disks I've used this way, can't really remember ever having a problem with 'em. Funny... I was looking through some of mine the other day and ran across 2 discrete disks: one labled 800kb and the other 1.0mb. Don't know what kind of life they lead before, but they're both 880kb Miggy disks now :-)
