Now there is the idea for a very useful peace of software to write.
Essentially it is the battery-changer application. All it does is write
parameter ram into a file, you change the battery, and you run it to restore
the locations from the file. Then this little problem could be solved by
saving P-ram before using appletalk and restoring it after. A nice option
would be to ignore clock bytes so the time doesn't get futzed. Any takers?
I'm on vacation...
