Re: Dirty Roms
Since I haven’t seen IM Vol 6 yet, other then the memory manager routines in the
macIIx, macIIcx, SE/30 roms. What other areas are 32-bit dirty in these roms?

Re: Dirty Roms
I’m not quite sure how to answer your question - if you are following Apple’s
Guidelines correctly, then you shouldn’t need to worry about what Toolbox routines are
32 bit dirty etc, providing you follow the rules about 32 bit cleaniness. But there are
some parts of the Toolbox/OS that are STILL 32 bit dirty even on 32 bit clean ROMs, as
they are internal features that would require more work to make them 32 bit clean. A
good example of where older ROMs will bite you with 32 bit dirty code is the Window
and Control Managers - read the TechNotes about using CDEF’s etc with 32 bit clean
code. Hope that helps answer teh question.

Re: Dirty Roms
I was wondering how much patching would be involved to get Mac II CX’s or SE/30’s to
work in the 32-bit mode of System 7.0. I hear Connextix Corp was working on such a
utility. Thank you for the info on the ROM’s.

Re: Dirty Roms
Yes, I recently read a press release from Connectix about their MODE32 product that
basically allows 32 bit clean operation with non-32 bit clean ROMs - I will be
interested to see how well it works, when it is released. Connectix should be capable of
doing it correctly, as they did an excellent job with Virtual and Optima/Maxima.
