Hi!

We have an 8255 chip in our kit. The 24 port lines are available through 26 pin ribbon cable. What are the extra 2 pins on the cable for?

Thanks
Rohit

Since I don't know what your "kit" refers to I have two guesses

1. Power and Ground
2. No connection, because 26 pin connectors and cable are cheaper than 24 pin connectors and cable.
