Regarding multitasking and virtual memory being 60's and
70's technology.. Well it is preposterous to claim that
the first PC OSs _should_ have had those features.

Agreed. Even IBM's OS/360 arrived on the market in 1967
without multitasking.

They only arrived with 64k!

Proper multitasking computers of the day of the first IBM PC
had megabytes or big fractions thereof. Even the PDP-11/45
which was Unix's first fully competent mult-tasking host had
256k.


true.. I was referring to the personal computers.. I remember paying $300
for 16k of static ram for my SYM1 in 78
