Agreed, ARM3 had its limits and could do with some serious math-co + blitter
help if the latter had already existed.
One notable limitation, a 2 clocks memory cycle, memory speed couldn't keep
up limiting the processor to 2 to 4 Mhz.
Don't think cache memory had already been invented, if it was IMO ARM made a
bad decision not to include it.
After all transistor count for the 32 bit ARM3 was scaringly low compared to
the 16 bit Motorola and Intel parts of the time.
There must have been space left on the dice for a few kB.

68000 was exiting too, at the time I spent way more than I had to get a
Atari to play with it.
Then again that prof included essay questions in his exams like.
"Explain why in _your_opinion_ RISC and Transputter designs are inferior to
the CISC argitecture of the 68000"
Stating this was not your opinion would make you fail the exam.
Note: the group of the "other" processor professor was involved in the
development of the Transputter.

Cheers,
Theo
