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 inadvertently 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 inadvertently 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. There should also may be a small sticker on the daughter card marking pin-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.

Special Thanks to the Popeye Beta Testers

Special thanks to the Popeye beta testers    James H.  John G.  Mark V. and  Tom C.   Without their valuable and timely help I would not have been able to complete this project. Thanks Guys!
