The 68000 series had alignment restrictions (as did the PDP-11). Pretty sure that a bunch of the bigger, older iron of the 70s required alignment for most of their data types.
Alignment requirements predate RISC by a fair amount, across many architectures.
- hga 11y agoAh, yes, the PDP-11 "bus error", SIGBUS. I remember hitting one of those in the early '80s and having to look up what it meant. So, yeah, in my personal experience over the years the architectures without hard alignment restrictions were less common. I suppose lacking them except for speed didn't hurt adoption of the Intel x86 family.
