Myself, while fiddling around with the standard RAMdisk /RAM, I discovered
that one could save the secondary bank's screen to an empty /RAM and it
will be positioned perfectly.  I sent this into A+ (or was it inCider...)
and they said it didn't work on all systems, but I have yet to find one
that it didn't work on.  Much easier than having to fool around with a
special ML routine.  I wrote a simple graphics program in AppleSoft to
work with this method.  Shall I dig it up and upload it to the .binaries.
group?
