CS/A65 computer system with GeckOS

GeckOS/A65, when running on the CS/A65 computer system, can manage up to 1 MB of addressable RAM (specifically, 256 blocks of 4kB via an Memory Management Unit [MMU]). While the base Gecko board provides 32 kB RAM, the system is designed to support much larger, banked memory configurations.

The CS/A65 is a modular, 8-bit computer system based on the 6502 processor, designed as a PET-compatible clone with advanced features. It features a passive backplane for I/O boards, a Memory Management Unit (MMU) allowing up to 1MB of address space, and support for multitasking via the GeckOS/A65 operating system.
