Locate the main board again and we will finish it up.
40. Install CON2, the thirteen pin connector. Insert it in the holes as
shown in the diagram, making sure that the leads point to the back of the
board.
41. Install CON1, the 34 pin connector using the same procedure as
before. This connector may consist of two pieces, one 20 pin and one 14
pin connector. If so, place them together on the board to make one 34 pin
connector. Check all of your solder joints on the two connectors before
proceeding. Remember that you are responsible for damage that occurs to
the output devices, so you don’t want to goof up!
Now here comes some more fun! First check over all of your connections on
the display board as well as the main board, you sure wouldn't want to come
this far to make a mistake! Now it's time to join the two boards together.
42. Notice the holes in the main board and the display board where JMP-
A and JMP-B are located. Cut the piece of thick bus wire in two. Using the
two pieces of bus wire, install the jumpers to hold the main board and the
display boards at 90 degree angles to each other. Notice how there are
notches in the main board and display board to assist in aligning them.
Use the notches to align the display board with the main board, note how
the display board is mounted with the displays facing away from the main
board.
