Hence the description of Windows 95 as "a 32-bit extension to a 16-bit
patch to an 8 bit OS originally for a 4-bit chip written by a 2-bit company
that doesn't care 1 bit about its users."

Required? Ghu forbid. After doing a bunch of PDP-11 assembler work, I
found out that the Vax had 256 opcodes and foreswore assembly thereafter.
Still, that was nothing compared to the 1500+ opcodes of x86*. I think I
dodged a bullet.

AFAIU, some of them were significantly slower than their multi-instruction
equivalents.
