Added a new part of the program, which will "compile" the connections
into a text file, and then when a circuit is simulated there is approximately 
30X speed improvement.  You cannot follow the circuit as it is simulated.  
You press ENTER, and the circuit is done.

I've used the parallel input and output feature now, for simulation
of some logic for an A/D converter.  It works great.  Just got done
wiring up a toggleswitch/pushbutton switch for the Parallel INPUTS.

Once converted to assembly it will zoom.

I have the simulated circuit-to-DIP converter working also, so
I can draw out a logic IC with the logic editor, and associate
the INPUTS and the OUTPUTS with pins on the DIP graphic.  Now
you can watch a simulated circuit from the PCB CAD program!

I've got an interesting book about doing BASIC searches with
some neat flags and comparisons that will end a search when
it knows it won't find any more matches, and doesn't have
to search the whole list.  I think I can apply some of the
techniques to speed up parts of the program.

Now to add the code to utilize my I/O card for more than 8
ins/outs for circuit input/output.

I want to design a whole bunch of circuits, and run one
on each Apple II I have, one simulated circuit being
the input to another, through the parallel cards.
