Z8 encore GPIO

Please excuse my ignorance.  I just bought the 39.95 Z86423 Encore MCU
package.  This is the unit that only has three leds (one red, one
yellow, and one green) instead of the led matrix array.  I have gotten
the serial port to work and can see printfs, but I would like to play
with the GPIO ports.  However, it seems that these ports are connected
to holes in the PCB.  As far as I can tell, these holes are designed
to be filled with a type of jumper connector.  I was wondering if
anyone could tell me how to connect to these IO pins.  I have worked
with an HC11 development kit, but the IO pins in that kit were
connected to a preinstalled connector designed to insert wires.  Any
help is appreciated

There are pins you can buy to solder into the holes. A local electronics place
might have some. The catalog I'm looking in calls them "Male Headers".
Essentially, each pin is a plastic block with a metal pin going through it. The
short side is what you solder into the board. The long side is for either wire
wrapping onto or to connect to a female header connector attached to another
board or to a cable. I use wire wrapping. I'm looking in a Jameco catalog
(www.jameco.com).
