Jerry,

No extra pins, but the modern EPP and ECP versions of the p-port
definitely add "programmability" to the equation... Jon E is using
this functionality in his PPMC project.

I don't know about an 8255 on a pcmcia card. Is this what you meant?
Or were you asking about an 8255 card for the PCI bus? I'll try to
look at my I/O "superstore" catalogs...

Hope this helps.
