I have a 33 MHz 386 that has certain apps on it
that I can't migrate easily to a Pentium class
machine, and whenever I have to 'run' that machine
I am reminded how poor the inherent 'shielding' is
by the 'jamming' that machine does to CH 11 TV
and even an 800 MHz frequency that the local trunked
system uses. The layout and inter-chip wiring in those
days was gross, coupled with physically huge leaded
parts - compared to today's PCs with much improved
board layouts, BGA technlogy, judicious use of interlay
ground planes and apparently much more knowledgeable
use of multilayer boards which provide an environment
suitable for the stable, clean, non-glitched operation
of a 533 MHz front side bus.
