Bomb Jack Arcade PCB Upgrade Compatibility for Original Tehkan Hardware
Confirm whether your original Tehkan Bomb Jack arcade PCB is compatible with the HighScoreSaves Free Play and High Score Save upgrade. The kit installs at the Z80 processor location while keeping the original Bomb Jack game board in service.
Choosing the Correct Bomb Jack Arcade PCB Upgrade
A Bomb Jack cabinet, marquee, or control panel does not by itself confirm compatibility. Vintage arcade machines may have been repaired, converted, or fitted with replacement hardware, so the actual game PCB should be identified before ordering.
The HighScoreSaves Bomb Jack upgrade is intended for documented compatible original Tehkan Bomb Jack arcade hardware. Confirm the game board, Z80 processor location, CPU socket, and board condition before installing the daughter-card upgrade.

How the Bomb Jack Z80 Daughter-Card Installation Works
The HighScoreSaves Bomb Jack upgrade installs through the documented Z80 processor location on compatible original Tehkan hardware. A suitable 40-pin CPU socket is required for installation.
If the Z80 processor is already socketed, normal kit installation does not require soldering. If the processor is soldered directly to the PCB, a qualified arcade technician must remove it and install a compatible 40-pin socket before the daughter card can be fitted.
Before restoring cabinet power, verify Pin 1 orientation, processor alignment, processor pins, socket condition, daughter-card seating, and any designated original program-ROM locations identified in the Bomb Jack installation guide.
