Re: [CAD_CAM_EDM_DRO] Re: Palm CNC

Jerry,
I know people who make lots of money making these kind of controllers
for cheap. They buy 386 boards for pennies and sell resulting units for
thousands of dollars. The key here is a parallel processing - each board
computes its own task, under DOS.
What is a computer you buy in a store? It consists of a mother board,
power supply, drives ( floppy and hard drive).
Now , consider this: take a piece of a plywood, mount on it the mother board
and drives.Power them from one power supply. Stack them in some kind of a
box, connect them together so they could communicate to each other - you get
an extremely powerful controller.
I'm sure , there are people who are smiling reading this - they do it all
along for years.
Alex
