SITU-PAN is a front-panel switches simulator for the Commodore 64. It displays 8 virtual LEDs and 8 virtual dip switches on the screen. The LEDs display the bit pattern at the current address in memory. Via the keyboard, the switches may be toggled, a new bit pattern written into memory, and the address advanced. In this way, machine code programs may be entered into memory, and then run. SITU-PAN was written during RetroChallenge 2015/07 for the purposes of entering SITU-MON into an emulated C64.
