This is it more or less. Another 15 to 30 minutes to fill in the blanks.
QB has an ON TIMER(n) GOSUB UpdatesScreen ....   hard ware,  real time interrupt.
n is the number of seconds. For updating the screen every one or two seconds is about right.

Actually updating the screen only takes a few usec. The rest of the time the computer
is doing EFI stuff.

Here are some shots of the computer. The mother board is mounted on a .125 inch
thick plate with the 3.5" floppy and hard drive are bolted to the bottom.
Everything fits in about a seven inch cube. Very rugged chassis.

Paul,
 Is this the development hardware ??..............I presume the flying version will not have
the floppy and hard drive.............Remember I am barely able to operate a computer !!

Thanks,
Kelly Troyer

It is the development hard ware AND!!!!! the flying version.

They are one and the same.


Yes the floppy and hard drive are part of it. The hard drive and the floppy drive
may be replaced when I get the USB driver working with DOS.

Since the engine will run with out the EFI program running
it is possible to write programs while you are flying.  Then test them in the air
and if they cause the engine to quit stop that program and load an older program
that has worked in the past and restart the engine. I would only do this
with in gliding distance of an airport.

I am not kidding. You may think I am crazy :) The FAA will not certify this.
Then again they did not like my GPS approach back in 1990.

I know this sounds a bit unusual but my life  history has
been years ahead of inevitable developments.

It is however advisable to have a copilot looking out the windows
with a hand on the stick :)

Now a days Kelly you are the exception :) Children are growing up operating
smart phones. Most smart phones are beyond me.
