Actually, it's mapped to $D400-D41C, according to this book, but it may vary
for the 8185 (later 5v version).  There are a couple of sites out there that
offer loads of information on all of the commodore chips, in case we want to
use the CPU, RAM, etc. to get the player to work.

BTW, does anyone know how to turn a file (e.g. a .SID file) into a string of
raw data?  I was thinking for the 92, but the 86 would be fine as well.

Then why did microsoft release their own version of Java?!
