Just wondering, is parallel processing possible on the CE?
The CE's processor only has a single core. On Python calcs you can also run code on the ARM-based Python coprocessor, but since memory is not shared between the two, in nearly all cases you'd spend more time communicating with the coprocessor than it would take to just do the computation in a single thread.
You can certainly do concurrent programming on the CE, though the fact that you can't use user-defined interrupts on most CE revisions is a bit of a limitation.

You could use any interrupt (even NMI!) if you were in Z80 mode, but only being able to do that with assembly is a bit of a deal-breaker.
Well you can use IM 1 in z80 mode so handling user interrupts are possible in a way, but this would require a bit of messing around with. That being said I'm not sure what use-cases this would really be appropriate for apart from a proof of concept?
