numbers using floating voltages
Looking for a program I have seen before. It was code for the BS 2 that was a random number generator, it used the floating voltages of the unused pins to and a more (truer) random number response.

It is just an RC circuit, like this one attached that has a time contant of RC=.1 second. The values are not critical so long as they have an RC value between 10 milliseconds and the RCtime maximum. The wiring is shown as curves to indicate that you should do it with long wires, wrapped around the edge of your circuit board & CPU for example. You could also include something like a reverse biased LED (cathode to the pin, p0 and anode to Vss) and that would make the circuit light sensitive as well. Here is code:
