If you have info on upgrading a 520 from .5 to 2.5, then this is all
you need.  I had a 1040St and a pair of wire cutters, and it was
a 520 in no time! *:^)  From there it was a .5->2.5 project.

If the info you speak of is a .5->1M upgrade for the 520, then that
is a different story.  You'll need my info.

I was going to put some time into doing a nice writeup of the project
and then release the document as shareware.  It is so hard to hoard
info though, so I may just post it here.
