Some decades ago, I wrapped up a Z80 maschine. Later I red about something called(?) "wrap only": A pencil like tool with a holder for a smal wire reel on the top. The wire went in the middel of the "pencil" down to the tip, a wire wraping. The thinking are to go from wraping pin to wraping pin without cut the wire.
I have some reel s of that wire, and, I shoold like to try it; I have an smal Arduino "thing" to try out.
What are the tool caled, and whew to buy it?
