Exidy 440 Multigame Compatibility for Original Exidy Hardware

Confirm whether your original Exidy 440 arcade PCB hardware is compatible with the HighScoreSaves Exidy 440 Multigame Free Play and High Score Save Kit. The upgrade retains the original Exidy 440 PCB platform, controls, sound hardware, and supported gun system while adding the multigame daughterboards to the existing board stack.

Before You Order
Hardware: Requires documented compatible genuine original Exidy 440 arcade PCB hardware; identify the original CPU and sound boards before ordering
Processors: Compatible 6809E and 6809 processors are required and are transferred from the original Exidy 440 hardware to the appropriate HighScoreSaves daughterboards
Installation: Requires CPU- and sound-board daughtercard installation, transfer of the documented K7 and H9 PROMs, removal of designated EPROMs, ribbon-cable installation, and the documented PCB DIP-switch settings

Choosing the Correct Exidy 440 Multigame Upgrade

The HighScoreSaves Exidy 440 Multigame Free Play and High Score Save Kit is designed for documented compatible genuine original Exidy 440 arcade hardware. It operates with the existing Exidy PCB platform rather than replacing the game hardware with an emulator, reproduction board, switcher, or generic multicade system.

Installation is more involved than a single CPU daughterboard upgrade. The Exidy 440 kit uses a main 6809E daughterboard, sound daughterboard, separate 6809 CPU daughterboard, transferred original processors and PROMs, designated EPROM removal, and a ribbon cable between the sound-side daughterboards.

Original Exidy 440 PCB Compatibility

Genuine Original Exidy 440 Hardware The kit is intended for documented compatible genuine original Exidy 440 arcade PCBs. Access to both the CPU board and sound board is required during the documented installation.
Cheyenne-Style Hardware Is a Common Reference The current installation guide notes that many installations use a Cheyenne PCB configuration even when the cabinet may currently be playing another supported Exidy 440 title such as Crossbow. Identify the actual PCB rather than relying only on the game presently running.
Original Exidy Board Stack Remains in Service The HighScoreSaves daughterboards install onto the documented locations on the existing Exidy 440 CPU and sound boards while retaining the original cabinet hardware, controls, sound system, and supported gun hardware.

Exidy 440 6809E and 6809 Processor Requirements

The Exidy 440 multigame installation requires both a compatible 6809E processor and a compatible 6809 processor.

On the CPU board, the original 6809E is removed and installed on the HighScoreSaves main daughterboard. Processor Pin 1 orientation must be matched carefully when the CPU is transferred.

On the sound board, the original 6809 is removed and later installed on the separate 6809 daughterboard. That completed daughterboard is then installed at the documented C2/C3 processor location on the sound PCB.

Main CPU Board Installation Requirements

Remove the Designated Program EPROMs The installation guide identifies the original CPU-board EPROMs that must be removed before the multigame daughterboard is fitted. Save the removed components and document their original positions.
Transfer the 6809E Processor The original compatible 6809E processor is removed from the Exidy CPU PCB and installed in the processor socket on the HighScoreSaves main daughterboard.
Transfer PROMs K7 and H9 The current guide instructs the installer to remove the original PROM at K7 and the PROM at H9 and install both on the HighScoreSaves main daughterboard with the correct orientation.
Main Daughterboard Uses Three Socket Locations After the processor and PROMs are transferred, the main daughterboard installs into three documented socket locations on the original CPU PCB. All pins must align correctly before the board is pressed into place.

Exidy 440 Sound Board Installation Requirements

Remove the Original Sound-Board 6809 The original compatible 6809 processor is removed from the sound PCB and set aside for installation on the separate HighScoreSaves 6809 daughterboard.
Remove the Designated Sound EPROMs The current guide identifies the sound-board EPROMs that must be removed before the sound daughterboard is installed. Store the original parts safely and record their locations.
Install the 6809 Daughterboard at C2/C3 The transferred 6809 processor is installed on its HighScoreSaves daughterboard, and the completed module installs at the documented C2/C3 position where the original processor was removed.
Connect the Sound Daughterboards The supplied ribbon cable connects the 6809 CPU daughterboard to the sound daughterboard. Cable orientation and seating should be verified before the original Exidy PCB stack is reassembled.

Exidy 440 Pre-Order Compatibility Checklist

1. Confirm Genuine Exidy 440 Hardware Identify the actual original Exidy 440 PCB hardware in the cabinet rather than relying solely on cabinet artwork, game title, or the game currently running.
2. Confirm the Original Board Stack Works Verify that the Exidy 440 hardware is fully operational before beginning installation. The current guide specifically recommends confirming a 100% working game board first.
3. Verify the 6809E and 6809 Processors Confirm that compatible 6809E and 6809 processors are available for transfer to the HighScoreSaves daughterboards or select appropriate processor options on the product page when needed.
4. Inspect the EPROM and PROM Locations Confirm that the designated program and sound EPROMs can be removed and that the original K7 and H9 PROMs can be transferred as documented.
5. Review the Complete Installation Guide Review processor orientation, PROM placement, daughterboard alignment, ribbon-cable routing, CPU-board DIP settings, and sound-board DIP settings before beginning installation.

Exidy 440 DIP Switch and Board-Stack Considerations

CPU-Board DIP Switches After the main daughterboard is installed, the current guide instructs the installer to set the documented four-position DIP-switch bank on the CPU PCB to OFF.
Sound-Board DIP Switches The documented eight-position DIP-switch bank on the sound PCB is also set to OFF before the Exidy 440 board stack is reassembled.
Label the Original Connectors Because the CPU and sound boards must be separated during installation, label every disconnected cable and connector and record its orientation before removing the PCB stack from the cabinet.

After Confirming Exidy 440 Compatibility

Once the genuine Exidy 440 PCB hardware, 6809E and 6809 processors, PROMs, EPROM-removal requirements, DIP-switch settings, and daughterboard installation have been confirmed, use the individual product page for the complete game collection, menu and gun-selection features, Standard and Wi-Fi choices, included components, current pricing, options, and ordering information.

This category is intended primarily to determine whether original Exidy 440 hardware is suitable for the HighScoreSaves Exidy 440 Multigame Free Play and High Score Save Kit before an order is placed.

Exidy 440 PCB Compatibility FAQ

Which arcade hardware supports the Exidy 440 Multigame kit?
