PowerPC has both segmentation and paging. Segmentation

If someone tells me you can turn off the segmentation
logic in some variant of PowerPC, I might change my mind
about it. :)
Agreed. 6502 expanded to 32 bits would be very nice.
Some changes would be needed to make it gogofast, like
a good cache system and possibly a more load/store
orientation and more registers. Which is pretty much
what ARM is.
Have you looked at the ARM instruction set? It actually has
a lot of similarity to a "stretch" 6502. :)
Imagine if the same amount of effort was applied
to a sensible machine, like MIPS, Alpha, or ARM!
Or PowerPC :-) Or even a 64 bit-wide Z80 :)
I'd like a 64-bit 6502 myself. Someone is working on a 32-bit one, however.
