# Display File Explorer

Short BASIC type-in program and explanation demonstrating the structure of the TS2068 display file (6144 bytes starting at address 16384). Shows how each byte encodes an 8-pixel row, and how POKEing 255 fills the screen in a distinctive three-section pattern useful for understanding screen memory layout.
