Nope, not all of us. ;)
In any case, I would imagine that the DOS version of
AutoCAD in
1982 wasn't using anything better than CGA. Some of the dev
notes for AutoCAD-80 note that work got done faster because the
CP/M port relied on more intelligent output devices that needed
less low-level control than the IBM and Victor 9000 ports.
I ran AutoCAD 2.17B for a long while in the mid-80s on an 8MHz 8088.
My display adapter was a CGA. It wasn't pretty (there was nothing at
all that was "pretty" about CGA output) but it was usable.
