Indeed. Have fun implementing a multitasking OS with only one stack, for example.

Can't you do tst rx on x86 with just mov rx,rx or something like that?

Only arithmetic left shift is redundant, though.

Couldn't agree more. Having 16Mb address space on the 68000 is fantastic. Sure, in 1979 that would've been a bit much, but Motorola was clearly thinking of the future here. Same with the brilliant idea of making the instruction set 32bit.
