You can use any KS roms that are for the A3000.
My A3k origonally had the KS 1.4 roms, I now have KS 3.1
roms installed. Pay close attention to how you remove the
old chips and install the new ones the same way. Most rom
towers are marked wrong and its easy to install the chips
in the wrong socket (beleave me.. I just did it :-D )
