A Simple Parallel Port Tester Board

Category: Computers and Hardware

I have this
forum.linuxcnc.org/39-pncconf/32400-mesa...pport?start=60#89231
A box with 17 resistors and 17 LED's, a male and a f-male port, nothing else.
Not versatile as yours, but it has also the option of connecting between the PC and machine and monitor in real time.

No ICs and no transistors required.
