Silk Worm High Score Save Kit Compatibility
Verify compatibility before ordering the Silk Worm high score save kit for documented compatible original Tecmo Silk Worm arcade hardware. The HighScoreSaves daughter card installs at the original Z80 processor location while retaining the original Silk Worm PCB as the operating game platform.
Choosing the Correct Silk Worm Arcade PCB Upgrade
The HighScoreSaves Silk Worm upgrade is designed specifically for documented compatible original Tecmo Silk Worm arcade hardware. Compatibility should be confirmed from the actual PCB and processor configuration rather than cabinet artwork alone.
Before ordering a Silk Worm high score save kit, verify the original Silk Worm PCB, compatible Z80 processor, socketed CPU location, daughter-card clearance, and installation requirements shown in the installation guide.
Original Tecmo Silk Worm Hardware
Silk Worm Z80 Processor Requirements
Silk Worm Daughter-Card Installation
Installation begins by locating the original Z80 processor on the Silk Worm PCB. If the existing compatible processor is being reused, it is removed from the original socket and installed on the HighScoreSaves daughter card.
The assembled daughter card is then installed into the original Z80 socket. Before restoring cabinet power, verify Z80 Pin 1 orientation, processor-pin alignment, socket condition, and complete daughter-card seating.
Daughter-Card Clearance
After installing the daughter card, inspect it from multiple angles and confirm that every pin is correctly seated in the original CPU socket.
Also verify that no original PCB component or test point contacts the underside of the daughter card before applying cabinet power.
Silk Worm ROM Saver Compatibility
The Silk Worm kit supports ROM Saver functionality. The documented original program ROMs may optionally be removed after the kit is installed and configured as directed.
Program ROM removal is optional. Follow the installation guide carefully and remove only the specific program ROMs identified for this supported configuration. Store any removed original components safely and document their locations.
Original Tecmo PCB vs. Replacement Hardware
The HighScoreSaves upgrade retains the compatible original Silk Worm PCB as the underlying arcade platform.
