# Three Tips from Rex Lundgren

Three hardware/software tips for TS2068: (1) Adding a third diode to the earphone input circuit (near CR5/CR6) to raise logic level and improve cassette loading reliability at lower volume settings; (2) DC power supply notes for external cassette recorders using an LED as a voltage-drop element; (3) Joystick Sketcher BASIC program using the STICK function to draw on screen with the joystick.
