Unlock the full capacity of your vintage system with the Commodore VIC-20 32KB RAM Expansion Cartridge. Running at the absolute physical boundaries of user-addressable RAM maps, this modern expansion lets you run complex 3D rendering engines, graphic adventures, heavy basic tools, and larger compiled hardware programs without having to shuffle memory blocks.
Modern Dynamic Configuration
In standard vintage hardware setups, adding memory to a VIC-20 had to be managed very carefully. Because certain software packages utilize custom block mapping architectures, some require exactly 3KB, 8KB, 16KB, 24KB, or 32KB of added space, while crashing if the wrong configurations are active. This card solves the issue completely with its onboard, high-quality configurable configuration switches (DIP switches).
Fully Switchable Address Blocks
Each individual memory area (Blocks 1, 2, 3, and 5) can be disabled or mapped separately with the toggle of a dedicated micro-switch. Pop it into your rear cartridge slot and flip the memory bank options instantly, giving you full master control to dial in specific retro program configurations in seconds.
- Maximum 32KB Upgrade: Easily boosts the stock 5KB VIC-20 up to a whopping 37KB total memory ceiling.
- Engineered in the USA: Built using durable multi-layer epoxy boards with precision gold-plated edge connectors for low-resistance system socketing.
- Integrated Reset Switch: Save wear on your primary power toggle with a handy reset button built onto the top cartridge board.
