the dumbest computer design decision ever made. In addition to that, Intel
was telling people to get ready to jump to iAXP432 because 8086/80286 was
nothing but a stopgap, and anyway the 80286 was for high-end minicomputer
replacements, so why assume that more than 1M on an 8086-type CPU for PCs
for an OS that was going to be obsoleted anyway was the future.

The 640K is a minor point.Look at the PDP 11 you had hoards virtual
memory but code and data only 64kb each. Same as the Intel's small
model. How long were OS's crippled by this fact?
Did the iAXP432 just have 64kb segments as well?
