Doubtful. We fixed a lot of problems with memory management when Apple
went to PowerPC. The 68K runtime has major problems dealing with large
chunks of memory.
Running a big simulation on MacOS 68K is a chore.
I'm actually very curious to hear details about that, if you have the time. What
kind of issues?
If I recall correctly you run into linkage issues with size of global
data, and sizes of offsets, and this sort of thing. It was really geared
towards 16-bit sized things; the 32-bit-everything model arrived quite
late and wasn't a panacea.
Even the Apple compilers weren't great at building large software.
