# A Cozy Nook for Machine Code in the TS2068

Identifies a 323-byte area starting at address 25365 (in single-display mode) used for bank switching that can safely store machine code when bank switching is not in use. The author tested loading zeros and machine code there without difficulty to normal TS2068 operation. Also notes unused fixed addresses in the system variable area at 23681.
