1RE: Simulator

[aiiadict@hotmail.com (Rich J.)]

I have graphic output working and
also parallel card input for 
simulation of circuits.

It takes a while to draw
initially. XDRAW is used for
gate symbols, HPLOT for 
connections.  I won't change
the color of the wires for
indication of "1" or "0" 
state because it would take
too long, so:

+5V or a "1" is represented by
highlighted connection points
on the inputs/outputs of gates.

Input can still be taken from 
the keyboard,  and I added a 
"programmable" data input, so 
you can set the input values 
for each cycle of the circuit 
and they will automatically 
be input one after the other.

The clock I have set up on
one of the Parallel card 
INPUTS and it works as a
clock.  I push a pushbutton
on the input to cycle it.

Next:
Input a real, useful circuit
and see how long it takes to
figure out the output.
