You can fit a lot on the floppy, a darn lot. If you haven't tried it and have a fast PC I recommend that you try downloading one of the 64 kilobyte (PC) demos from BTTR. If you take for example the Farbrauch 8th demo. (I think RCK posted a link to that somewhere here) you'd find it has a ridiculous amount of graphics and music squished down in 64 kb.
