Leta Replacement Upgrade

Atari AVG Custom Chip Replacement The Atari AVG Custom Chip Replacement is designed as a direct substitute for the original Atari AVG chip (Part Number: 137179-001). This custom component functions as the Gate Array / Address Controller used in Atari vector arcade hardware, handling critical addressing and control tasks required for proper system operation. Because the original Atari AVG chip is long discontinued and increasingly difficult to source, this replacement solution provides a reliable option for repairing and restoring classic Atari arcade boards. It is engineered to replicate the functionality of the original DIP package chip while allowing collectors and technicians to keep their vector-based arcade systems running. This chip is commonly used in Atari vector arcade machines where the AVG (Analog Vector Generator) system manages the generation and control of vector graphics displayed on the monitor. Proper operation of this chip is essential for stable gameplay and correct vector drawing. Key Features Replacement for Atari AVG custom chip Compatible with original part number 137179-001 Implements the Gate Array / Address Controller function Designed for repair and restoration of Atari vector arcade boards Helps maintain long-term operation of classic Atari vector systems

Star Wars / Empire Strikes Back 12K VRAM Upgrade The Star Wars / Empire Strikes Back 12K VRAM Upgrade is a reliable, plug-and-play solution that replaces the six 2K × 8 VRAM SRAM chips on your Atari Star Wars vector PCB. This modern upgrade reduces failure points, improves long-term reliability, and keeps your classic game running smoothly for years to come. Features · Compatibility · Installation Notes · FAQ Key Features Drop-in module replaces six 2K×8 VRAM SRAMs (12K total). Plug-and-play on socketed boards—no ROM or wiring changes. Modern components improve stability and longevity. Reduces heat and common failure points in the VRAM section. Compatibility Atari Star Wars (1983) and The Empire Strikes Back (1985) vector arcade PCBs/cabinets using the standard 12K VRAM section. Installation Notes Power off and discharge the cabinet before service; observe ESD precautions. Align the module with the VRAM positions and press firmly into the sockets. No soldering required if your original VRAM chips are socketed; if not, sockets must be installed by a qualified technician. FAQ Do I need to modify the board? No. On socketed boards the module drops in—no wiring or ROM changes. Will this change gameplay or graphics? No. It’s a reliability upgrade only; gameplay and timing remain original. What issues does this address? Replaces six aging VRAM chips that commonly cause intermittent video faults, instability, or no-boot conditions.

6100 Deflection Board LV Section Replacement Module The 6100 Deflection Board LV Section Replacement Module is designed to replace the unreliable low-voltage (LV) section found on the Atari 6100 vector monitor deflection board. This upgrade eliminates several common failure points that can cause instability, monitor shutdown, or inconsistent operation. Over time, the original low-voltage circuitry on the 6100 deflection board can become unreliable due to aging components, heat stress, and repeated power cycling. This replacement module modernizes that section of the circuit and provides improved reliability while maintaining proper monitor operation. Once installed, the module restores stable low-voltage regulation for the deflection board, helping ensure your vector monitor operates correctly in classic arcade machines such as Tempest, Star Wars, Major Havoc, Quantum, and other Atari vector cabinets that use the 6100 monitor. Key Features Replaces the original low-voltage section of the Atari 6100 deflection board Eliminates common LV circuit failure points Improves long-term reliability of the vector monitor Helps stabilize monitor operation and voltage regulation Designed for arcade restoration and repair work Compatibility Designed for use with the Atari 6100 vector monitor commonly found in classic arcade machines such as Tempest, Star Wars, Major Havoc, Quantum, and other Atari vector titles. Installation Notes Soldering and de-soldering are required for installation. The module installs directly onto the 6100 deflection board as shown in the gallery images. Installation should be performed by someone experienced with arcade PCB repair. This upgrade is an excellent solution for arcade collectors and technicians restoring original Atari vector monitors who want improved reliability without replacing the entire deflection board.
