Hi guys

I need a breakoutboard for my second paralell port to make the buttons on my controlpanel connect to my computer.

Do I need a seperate BOB, or can I use the +5v on the other bob as long as i connect the grd´s, or is there a common ground in the pc that takes care of this?
Of course this would not be isolated in anyway, but can it be done?

I run a secondary paralellport driving 2 servos in step/dir, and a driver/bob for the stepper on the z axis.
This bob only have homing, limit/emergency input and 3 outputs.

Running my machine today wit just an old printercable stripped at the end and the wires connected directly, but as I understand I need a BOB to get my 5v from the specific paralell port , as i dont see any +5v on the paralell port pinout.

I guess the 5v on the other port/bob is transformed from the powersupply on the board, am I correct+

So need a tip of what BOB to get to make this good, easy fast and cheap....hmmmm possible?... dont know, but the fast part could be nice:)

Bring it on guys, what do you recomed for a BOB intended only for I/O

Live in Europe so if anyone have any suppliers ther it is also interesting

Best reg
