Hi Doug!

I worked at Bell Labs back then and guess what? When we needed
good performance, we used VMS! The first release of UNIX System V
did not have demand paged virtual memory but VMS did so it was
significantly faster for big jobs like chip layouts and simulations.

A very simple chip back then (2.5 micron) took overnight on a dedicated
VAX11/780 to do the layout and simulation. Of course, this was a 1 MIPS
machine (and that is being polite.)

The original WeCo 3B2 mini computers were actually slower than even
the cheapest IBM PC running DOS partly because the UNIX 
implementations were so bad
(again no demand paged VM.)

On the outside we probably laughed at DOS and VMS but on the inside 
we knew the truth!

Enjoy the memories (some of them virtual and written to /DEV/NULL in my case!)

73,
Tony AA2TX
