Controls
Boots the DEC PDP-7 to a UNIX CONSOLE banner on the KSR-33 console teletype, then echoes every character you type (the machine is uppercase, like the real Teletype). Click the screen first so it captures the keyboard, or tap the on-screen keys and front-panel START / STOP / STEP. Open the debugger to single-step the 18-bit CPU one instruction at a time, watch AC / PC / L / MQ change in octal, set breakpoints on the program counter, and read core memory as octal disassembly.
