O4mega Memory Expansion PCB
ID: P-0014
O4MEGA - 4MB RAM Expansion for OMEGA MSX
The O4MEGA is a high-quality memory expansion board specifically designed for the OMEGA MSX computer. This expansion allows you to upgrade the native 512KB RAM to a full 4096KB (4MB) of RAM—the maximum capacity supported by the MSX mapper architecture.
Key Features:
- Massive Capacity: Increases total system memory to 4096KB RAM.
- Seamless Integration: Plugs directly into the dedicated J12 header on the OMEGA motherboard.
- Simple Assembly: Designed with a "Through-Hole" philosophy for easy DIY soldering (no SMD components or specialized programming required).
- Flexible Configuration: Can be populated with fewer SRAM chips (e.g., AS6C4008) to achieve 2048KB if a full 4MB is not required.
- Compatibility: Specifically engineered for the OMEGA MSX system, utilizing its integrated mapper circuitry.
Technical Specifications:
- Memory Type: Utilizes low-power AS6C4008 CMOS SRAM.
- Installation: Direct connection via J1 connector to the OMEGA's J12 port.
- System Support: Fully recognized by MSX2+ BIOS; functional in MSX2 environments (though boot-up counts may vary by BIOS version).
Note: This is an essential upgrade for OMEGA owners looking to run memory-intensive software, RAM disks, or advanced MSX applications.
