Your so completely wrong about this it isn't even funny. Apple spec. in (as
I remember) 1989 was for 32 bit clean apps. Apple started shipping 32bit
ROM with the Ci. If you had written software for the IIci and above you
would yes, have to re-write some of the apps header files to support the
new memory structure. If you followed the programming guidelines correctly
(and if you didn't that isn't Apple's fault) your app written in 1982 will
run just fine on OSX.

Say that about an app written for the Microsoft world. Hell, try to tell
me how an app written for Win98 runs well now.
