Robby Roto Multigame PCB Upgrades for Original Bally/Midway Z80 Hardware
Research the HighScoreSaves Robby Roto Multigame upgrade for compatible original Bally/Midway arcade hardware. This version of the multigame kit installs on an original Robby Roto PCB stack and continues to use the original Z80-based arcade platform.
The Robby Roto-based multigame configuration provides supported Robby Roto and Wizard of Wor gameplay from the compatible Robby Roto hardware platform. Compatibility for this category is determined by the original Robby Roto PCB and board-stack configuration, not simply by which game is currently being played.
This is an original-PCB upgrade rather than a replacement JAMMA board, reproduction PCB, generic multicade, or software-emulation system. The compatible Bally/Midway board stack remains the operating arcade hardware.
Robby Roto Multigame Installation Guide
Before ordering, verify that your cabinet contains compatible original Robby Roto hardware and confirm the Z80 processor, CPU socket, and board-stack arrangement shown in the installation guide.
Robby Roto Z80 and PCB Compatibility
The multigame upgrade uses a Z80 daughter card installed at the documented CPU location on the original Robby Roto hardware. A compatible Z80 processor must be installed on the daughter card; an existing compatible processor may be reused, or a replacement may be selected when ordering.
- Designed for compatible original Bally/Midway Robby Roto arcade hardware
- Uses the original Robby Roto board stack as the underlying game platform
- Uses a compatible Z80 processor mounted on the HighScoreSaves daughter card
- Requires a suitable 40-pin Z80 socket at the documented CPU location
- Provides supported Robby Roto and Wizard of Wor gameplay from the Robby Roto hardware configuration
HighScoreSaves designs and supports this multigame configuration for compatible original Bally/Midway Robby Roto Z80 arcade hardware.
Understanding the Robby Roto Multigame Upgrade
The Robby Roto Multigame Kit is designed around compatible original Bally/Midway Robby Roto hardware. Instead of replacing the arcade PCB with a modern game board, the HighScoreSaves daughter card works with the original Z80-based board stack and adds supported multigame functionality to that hardware.
This category specifically covers the Robby Roto hardware configuration. Correct identification of the original PCB stack is important because the installation method, Z80 location, and board arrangement are determined by the Robby Roto hardware itself.
Robby Roto Board Stack and Z80 Daughter Card
Original Robby Roto hardware uses a multi-board cage. During installation, the board stack is arranged according to the HighScoreSaves installation guide and the Z80 daughter card is fitted to the CPU board.
In the documented multigame configuration, the original memory board previously occupying slot 2 is no longer required. The remaining boards must be returned to their documented positions before the cabinet is powered on.
- Game board remains in slot 1
- Slot 2 remains empty because the original memory board is no longer required
- Pattern board is installed in slot 3
- CPU board is installed in slot 4 as documented
- HighScoreSaves Z80 daughter card installs on the CPU board
Z80 Processor Requirements
A compatible Z80 processor is required on the daughter card. An existing compatible Z80 may be reused, or a replacement processor may be selected when ordering. Correct Pin 1 orientation should always be verified before installing the processor or daughter card.
Robby Roto Multigame Support
The Robby Roto-based multigame configuration provides both Robby Roto and Wizard of Wor as supported games while continuing to operate from the compatible Robby Roto PCB platform.
When Wizard of Wor is played through this Robby Roto hardware configuration, hardware differences mean that the starfield background, sparkle effect, and speech are not available. These are characteristics of the Robby Roto-based configuration rather than selectable kit settings.
Original Robby Roto Hardware vs. Replacement Systems
The HighScoreSaves multigame kit does not replace the cabinet's original game platform with a generic multicade, JAMMA replacement board, or software-emulation system. Compatible original Bally/Midway hardware continues to provide the underlying arcade platform.
Why Keep the Original Robby Roto Hardware?
- Retains compatible original Bally/Midway arcade hardware in the cabinet
- Keeps the original Z80-based Robby Roto board stack as the operating platform
- Adds supported multigame functionality through a dedicated daughter-card upgrade
- Avoids replacing the cabinet with a generic multicade or emulation board
- Keeps the installation focused on the original Robby Roto hardware architecture
What to Check Before Ordering the Robby Roto Multigame Kit
Original arcade cabinets may have been repaired, converted, or assembled from different boardsets during decades of service. Inspect the actual hardware before ordering rather than relying only on the cabinet artwork or game currently displayed.
- Confirm that the cabinet contains compatible original Robby Roto hardware
- Verify that the existing board stack is working correctly before installation
- Locate the Z80 processor position on the CPU board
- Confirm that the CPU location has a suitable 40-pin socket
- Inspect the processor pins, socket, connectors, and board-stack hardware for previous damage or repair work
- Review the Robby Roto Multigame Installation Guide before ordering or beginning installation.
