Never mind! Found one a few pages into the forum. Didn't come up in my searches... sorry for the noise.

Thanks!

Oh thank you completely missed that great package on the download page.
That's going to help a whole lot.

Can someone show how to implement the reset part of flip flop, such as J-K in logiccircuit?
Most data sheets show "transmission gates" involved in the reset function.
The simulator does not have these primitives.
Graphic Attached.
Is there another way? I've looked at a lot of diagrams on google and ...

Maybe consider first the lowest cost programmable logic boards-
something that hobbyists would use, ie: I just got a $30 MAXII kit off ebay.
Perhaps you could provide a bundle that works together and get this into the "MAKE" ecospace.

Why thank you.

Has output for FPGA been considered?
VHDL, Verilog...

Implementation of a 74HC520 if you need it.
I take it there really isn't a library of all the LS parts somewhere...
I'll keep uploading them as I make them if not.

My thanks extended to the creators of this program!

Simple button and LED test harness.
This exposed that the MR line had a inverter along the way that flipped the line the wrong way.
Test is documented in the file.
