You need a Stamp Tester.

Stamp Tester, Newzed?·

I wonder if anybody makes such a thing...

Newzed

You're joking, of course, PJ.· I have been making them for a long time.

Here is a picture of one.

Yes, Newzed, but you no longer include your/that link with your signature.

Newzed

I know, PJ, but you can only have one link.· Right now I'm into Propeller stuff.· I'll go back to the Stamp Tester in a week or so.

"Removing the wires" converts your 'input' pins into antennas. An 'input' left 'floating' (connected to nothing, in other words) has no guaranteed value. If you really want that to work, you need to add a 10K ohm 'pull-down' to the wire network -- or to each pin. Really, if the pins are all wired together, you only need one pull-down resistor to Vss (ground) to insure all the inputs get a 'hard' zero to read.
