"description": "64KB SRAM that also renders the Galaksija 32x16 text screen from its own video RAM (0x2800-0x2BFF) into a 256x128 framebuffer on a ~30fps timer. Reads from real memory (not snooped writes) so the picture is correct regardless of chip load order. Yields reads of 0x2000-0x203F to the memory-mapped keyboard. Phase 3 chip-to-chip bus proof.",
