Paralell port questions

i would like to create a control panel and I already have an MPG2 using my second port.

can I add another port and wire it to a breakout board so that input signals could be used such as switches and such?

Thanks

Yes, you can basically add as many parallel ports as you have slots for
(I think 8 ports is the maximum)

Those work:

Hi

The 9865 chip based card emcPT pointed to should work fine.

Just be aware that CNC4PC are very expensive, you can buy a similar card from Amazon for $9.95 and probably get one from ebay or newegg for $5

If PCI slots are at a premium, the dual headed twin port cards work well too
