Ughh, DOS.  Just kidding (sort of)..

Anybody here work with a Real-time OS?  I have always been kind of
curious about how a real time version of Linux differs from a regular
one.  Just stripped out?  I'd think a real-time OS would be good for
something like engine management and monitoring..

Matt-

Me. I wrote my own real time OS back in 1976 on a 6502 in assembly language.
My road test system would take in data every few milliseconds process it,
display on the instrument panel with an LCD, and send it to the printer in
real time while the printer is printing. All using a ONE megahertz processor
and 2K of EPROM and ONE K of RAM! I also designed and manufactured the SuperKIM
mother board. Probably the first commercial application of an embedded microprocessor.
For sure the first real time multitasking microprocessor software. Before the Apple II.

Well When Windows came out they busted a lot of real time applications because
you could directly access the hardware using QB running on DOS.
There were instructions called IN and OUT that directly accessed the
hardware at light speed. PEEK and POKE did the same thing.
All that is gone.

Paul Lamar ...No rotor no motor.


Here is the prototype Matt. I went out to the hangar and dug it up.
Road & Track used it for about five or ten years to
test cars. This is one of the very first Kim 1s.
Note; the ceramic packaging and gold pins on the CPU
and ROMs. I now have it back. The Superkim computer was used
in the production model for years and then we redesigned it
keeping most of the features but doing away with the keyboard
and six seven segment LED.

John Dinkel (on here) wrote a few articles about it.
