Silk Worm Free Play and High Score Save Kit

Silk Worm Free Play and High Score Save Kit for Tecmo Arcade PCB

Upgrade a compatible original Tecmo Silk Worm arcade PCB with permanent Top 10 high score saving with initials, Free Play, attract sounds, menu-driven settings, ROM Saver, practice features, and optional Wi-Fi leaderboard support while retaining the original arcade hardware.

The HighScoreSaves daughter card installs at the documented Z80 processor location on compatible original Silk Worm hardware. This is an original-PCB upgrade rather than a replacement JAMMA board, reproduction PCB, generic multicade system, or software-emulation platform.

Choose Your Silk Worm Kit Configuration

Select either a Standard Save Kit for local score and settings storage or a Wi-Fi Enabled Kit that adds qualifying online score submission to the HighScoreSaves leaderboard.

Processor and compatible 40-pin Z80 socket options may also be selected when needed for compatible original Tecmo Silk Worm hardware.

Silk Worm Two-Player Mode, God Mode, and Score Tables

Two-player Silk Worm operation requires coin play. Two-player mode is not available while the game is operating in Free Play mode.

God Mode provides unlimited lives for practice and testing. High scores are intentionally not saved while God Mode is enabled.

Separate supported high-score tables are maintained for 2, 3, and 4 lives settings so scores achieved under different lives configurations remain independent.

Silk Worm Installation Requirements

• Original PCB: Designed for documented compatible original Tecmo Silk Worm arcade PCBs
• Z80 Processor: Requires a compatible Z80 processor on the HighScoreSaves daughter card
• Socketed CPU Location: The documented Z80 location must use a suitable 40-pin socket for daughter-card installation
• Already Socketed: No soldering, trace cutting, or special wiring is required when the Z80 location is already properly socketed
• Soldered CPU: If the Z80 is soldered directly to the PCB, a suitable 40-pin socket must be installed before fitting the kit
• Z80 Installation: The existing compatible processor may be transferred from the PCB to the daughter card, or a compatible replacement may be used
• ROM Saver: Remove only the designated program ROMs identified in the Silk Worm installation guide
• Before Power-Up: Verify Z80 Pin 1 orientation, daughter-card seating, processor-pin alignment, CPU socket condition, and underside clearance

Does the Z80 processor need to be socketed?

Yes. The documented Z80 processor location must use a suitable 40-pin socket before the daughter card can be installed.

Do I need to solder anything?
