It looks just as good as hand tuned bitmaps at those sizes. And when you go to
the printer where a bitmap might not exist, it works better. We've got a
bunch of MacPlus (1 meg variety) hooked to imagewriter II's running MacWrite
II printing out hundreds of pages (with type from 72 point down to 4 point)
for passing out as Seybold. The type looks better than anything I've ever
seen from an ImageWriter.

Yes, from 64K to 8 megs.

>What is the minimum memory I can get away with using for it?

A one meg plus, with enough RAM for the cache and ATM - exact details not
set yet because ATM is still being tested.

>How many fonts can be stored in a cache?

A rough estimate is 50K per outline, but I've run 4 outlines on a 96K cache
on a two-floppy plus w/no hits to the disk after the fonts are first imaged.

>How long does it take to generate the fonts on a stock Mac Plus?

This depends on how full the cache is and what size you initially want (plus
whether you use floppies or a hard drive) - in my two-floppy configuration
about 5 seconds a outline, then in realtime use after that - i.e. I couldn't
out type it.

>What happens when the cache is filled?

The cache is LRU, so technically you could get a case of thrashing, but we
have yet to see one. If it fills up, something will be purged to make room.

The current 'readme' notes on ATM say it nees 128K plus the cache size - that
might not be an exact number since ATM is still in testing/development. Once
the fonts are in the cache I haven't noticed any speed slowdowns. I've used
it on the Plus and was surprised at first how I could do real work with 1 meg
and two floppies (my first time w/o a Mac II since they came out :-() Hope 
this information helps.
