Akai's site is missing some operating
systems right now. I've put some here
for the time being. The underlined models
are here.

For now, these will only link to the page on Akai's site that contains the files. I do have all of the Operating Systems and will put them up here if you cannot access Akai's site. Note that you will need a program called O.S. Maker to get some of these onto a floppy
from your PC. This program is available on Akai's site as well.
