# That is not the problem; one can do memory management and multiple
# address spaces in external hardware as well. But the MacOS architecture
# obviously wanted to be all in one address space, as did the early
# windows versions. This makes GUI easier and networking and fault
# isolation harder, but it's a valid tradeoff. :-)
Not really. It was known to be a problem from the first Multi-Finder. The original
Macs only ran one application at a time, and had to halt and return to Finder to
run another. That continued till the Multi-Finder in system 6 (or 5?), and
officially enshrined in system 7. By that time Apple already knew it was dead
end operating system and started and aborted a number of successors, and continued
warnings that all the low level interfaces would disappear Real Soon Now. Even
implementing on the PPC caused all sorts of compatiability problems.
On the other hand I'm still running 68K programs on MacOSX.
