Gravitar Free Play and High Score Save Kit
Product information "Gravitar Free Play and High Score Save Kit"
Gravitar Free Play and High Score Save Kit
Upgrade documented compatible original Atari Gravitar vector arcade hardware with Free Play, permanent Top 10 score saving, adjustable attract sounds, Fast Boot, Stealth Mode, ROM Saver support, on-screen settings, and optional Wi-Fi leaderboard submission.
The HighScoreSaves daughterboard keeps the original Atari vector PCB, controls, sound, timing, and vector display hardware in service rather than replacing the game board with an emulator, reproduction PCB, or generic multicade system.
Compatibility & Requirements
Gravitar Kit Highlights
Play without coins while retaining traditional Coin-Up operation when desired.
Permanently stores the Top 10 supported scores using serial EEPROM.
Reduces startup time so Gravitar reaches gameplay more quickly after power-on.
Boots directly into gameplay for a more stock-appearing startup.
Permanent Top 10 High Score Saving
Gravitar normally loses its high scores when cabinet power is removed. The HighScoreSaves kit adds permanent supported score storage using serial EEPROM.
Stores the ten highest supported Gravitar scores permanently.
Uses serial EEPROM rather than a battery-dependent score-save system.
Maintains separate supported tables for 2, 3, 4, and 5 lives settings.
Save and restore supported high-score data through the kit menu.
Atari Vector Monitor Protection
Gravitar uses an original Atari vector display system, where reducing prolonged static imagery is particularly useful during extended idle periods.
Attract Sounds and On-Screen Settings
- Adjustable Attract Sounds: Select 25%, 50%, or 100% attract rotation frequency.
- On-Screen DIP Settings: Adjust supported settings without opening the cabinet.
- Copyright Message: Select original manufacturer or HighScoreSaves branding.
- Reset Support: Restart the game without cycling cabinet power when the reset option is enabled.
Fast Boot and Stealth Mode
Gravitar Settings Menu Access
With the cabinet powered off, hold Player 1 Start while turning the cabinet on.
Release Player 1 Start when the on-screen prompt tells you to continue.
6502 Daughterboard Installation
The HighScoreSaves Gravitar kit installs through the documented 6502 processor location on compatible original Atari vector hardware.
Verify documented compatible original Atari Gravitar vector hardware before removing the processor or original program ROMs.
Confirm that the 6502 processor is installed in a compatible 40-pin socket.
Follow the current Gravitar installation guide for processor removal, daughterboard installation, processor placement, and correct orientation.
Before restoring cabinet power, verify Pin 1 orientation, processor alignment, socket condition, daughterboard seating, and every individual processor pin.
What If the 6502 Is Soldered to the PCB?
If the original 6502 is soldered directly to the Atari PCB, a qualified arcade technician must properly remove it and install a compatible 40-pin socket before the HighScoreSaves daughterboard can be installed.
Gravitar ROM Saver
The kit supports ROM Saver functionality for documented original Gravitar program ROM hardware.
Standard and Wi-Fi Enabled Kits
Wi-Fi can be disabled without affecting Gravitar gameplay, Free Play, local score saving, score tables, ROM Saver operation, Fast Boot, Stealth Mode, or on-screen settings.
Gravitar Kit FAQ
Which arcade PCB does this kit support?
The HighScoreSaves Gravitar kit is designed for documented compatible original Atari Gravitar vector arcade PCBs.
Which processor is required?
The Gravitar kit requires a 6502 processor installed at a compatible socketed 40-pin processor location.
Does installation require soldering?
No soldering is required when the 6502 is already installed in a compatible 40-pin socket. A soldered processor must be professionally removed and socketed first.
How many high scores are saved?
The kit permanently stores the Top 10 supported Gravitar high scores using serial EEPROM storage.
What is Fast Boot?
Fast Boot reduces startup time so Gravitar loads more quickly after power-on.
What is Stealth Mode?
Stealth Mode boots directly into gameplay for a more original stock-cabinet appearance.
Does the kit replace the original vector hardware?
No. The kit continues using the original Atari Gravitar PCB, controls, sound, timing, and vector display hardware.
Are upright and cocktail cabinets supported?
Yes. Current documentation supports documented upright and cocktail Gravitar cabinet configurations.
Is Wi-Fi required?
No. Standard kits save supported scores and settings locally. Wi-Fi is optional for supported online leaderboard submission.
