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."

The x86 stuff is about as far away from PDP-11 as you can get.  Required
to know it, but so unpleasant.

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.
