RE: How can I access the TINI IO Ports

The problem with me is that I couldn't find anywhere
to connect my LCD to the TINIs400 socket. Most of the
IO ports are used to chip select/enable signals, and
there are only Port5 and Port1 have some pins out on
the socket. I wonder is it possible to interface it
using the parallel IO pins on the socket?
