The ARM 2 chip in the early Archimedes machines was a 32-bit chip with 26-bit addressing so it got referred to as arm26 assembler (I'm not sure if that's technically -correct-, but I'm pretty sure it was in the title of the book I learned from and there's a directory in linux kernels that support that arch called asm-arm26 at least, so my memory isn't -just- making it up ;).
