Popeye High Score Save Kit -- Installation Guide
Step 0: Turn off power to the game
While it may be possible to install this kit without removing your
board from its cabinet, you may find it easier to install
the kit if you do remove the board.
In that case, pay careful attention (or label), any wire
connections as you disconnect your board so that you can
correctly rehookup the game PCB afterwards.
Take note of which side of the PCB edge connector is facing the
parts side of the board and which side faces the solder side,
This connector is typically not keyed and can be
inadvertantly plugged in backwards - ouch!
It is recommended that you label the connector faces
with something like "parts side" or "solder side".
Step 1: Locate the CPU board
The Nintendo Popeye boardset consists of two boards (video and CPU).
The CPU board is the one with the gold edge connector.
See example picture below.

Step 2: Remove the Z80-CPU chip
Locate and remove the Z80 chip on the CPU board.
Use the above photos to assist in locating it.
See Z80 Chip Identification
for additional information.
The Z80-CPU chip is a 40 pin (large) chip, located at 5J
located near the center of the board.
Remove the chip gently by using a flat head screwdriver
to pry it out of its socket from each end.
Be careful not to bend any of the pins.
If any pins do get inadvertantly bent, you will need to straighten
them out before the next step.
Needle nose pliers work the best for this.

Step 3: Insert the Z80-CPU into the daughter card
Insert the just removed Z80-CPU chip into the empty 40 pin
socket on the High Score Save Kit.
Make sure pin-1 is correctly oriented.
Pin-1 is marked on the Z80-CPU chip usually by some type of indentation
or circle molded into the plastic.
The end of the chip with the marking, needs to match up with the
socket on the daughter card that also has a marking on the plastic.
Pin-1 is also labelled on the kit pcb with a "1".

Step 5: Insert the daughter card into the CPU board
Insert the daughter card back into the Z80-CPU socket on the
CPU board where the Z80-CPU chip was originally removed from.
Again, make sure pin-1 of the Z80/daughter card is oriented
to correctly match pin-1 on the CPU board.
Use the photos as a guide.
The header on the daughter board has pins that are more
heavy duty than the original Z80-CPU pins, thus you will need
to press very firmly to get the daughter card to be fully
inserted into the original Z80-CPU socket.

Step 6: Double check your work
Review the steps and double check that Z80-CPU is properly
installed into the daughter card with no bent pins and that
it is correctly oriented for pin-1.
And that the daughter card is also installed snug into the
Z80-CPU socket at 5J with pin-1 matched up.
Step 7: Powerup and game and enjoy!
Reinstall your board into the cabinet if necessary, and then
powerup your game.
This is a good time to also put the game into test mode and
verify the DIP settings.
See Popeye Test Mode and DIP settings.
If the game does not come up, turn power off immediately,
double check your work, and read over the
trouble shooting section.
