A bare bones TTL electronics simulator created by Neil Bauers. It is useful for BTEC Computer Systems and other Electronics courses such as the AQA AS and A2 courses.
It is a really simple program. There is no copyright so do what you like with it.
You can download or run this gate simulator program (for Windows 95, 98, ME, 2000, XP Etc). Here is the help file.
Right click to add gates to your circuit.
Single click unconnected inputs to toggle them between 0 and 1.
You can connect gates by dragging a wire from an output to an input. Dragging the other way does not work.
