4. Remove the three connectors. (Figure 4, #1 is a two -
pin; #2 is an 8-pin; and #3 is a 50-pin ribbon cable.)
a) The 50-pin connector is difficult to remove. Use a
small screwdriver and gently pry it loose from one
side; then gently rock the connector back and forth
until it comes free.
b) On new main CPU boards, the connector with the
tabs is used to make it easier to remove.
