Somebody from Apple flaming about changing the rules in mid-game? A case of the pot calling the kettle black. Remember switcher?

Am I on drugs? Or what? But in spite of your attitude I tell you what it means. All it means is that the exception frames vary between different members of the 680x0 family. Hence an exception handler may require a rewrite to work with a 68020. The 68000 and 68008 use the same stack frames, the 010 has a few changes and the 020 has a number of new frames. I believe the 030 has same set of frames as the 020. Jerry Whitnell Lizzi Borden took an axe Communication Solutions, Inc.
