You could format 720K floppies but not 1.44MB ones. You may
be able to
buy some $10 old dos games on 720K floppies - toss the game keep the
floppy.

Can't you simply format 720K or 1.44MB floppies as 400K ones? ISTR, I used
720K ones on mine.

I have purchased new 720k floppies on eBay for about $25 per hundred. You
can also get them 10 at a time. These are also sold as 800k for Apple (same
media, different format).
The 1.44M diskettes have a different oxide than the 720k diskettes. The 720k
disks have one hole for write protect while the 1.44M has a second hole. The
new drives sense the hole and adjust the write current for the different
oxide. You can cover the extra hole on the 1.44M disks and formatted it as
720k but this will cause problems (I have been told).
I don't know about the Lisa 400k disks but I format 720k disks in single
density mode (360k) for my SWTPC 6800 system all the time.

I used to do that for my old Mac SE - cover the hole on a 1.44m floppy
to make it a 720k - and it works ok. It is sort of a one-way deal,
though. I could never get them to format back to 1.44. I also have no
idea what it was doing to the drive. Nothing, I think, as my son still
has that SE.
