Boots straight into Spacewar! (1962) on the emulated DEC PDP-1. Two ships duel around a star: player 1 uses A / D to rotate, S to thrust, W to fire and Q for hyperspace; player 2 uses J / L, K, I and U. Tap the on-screen control panel, or use the keys after clicking the screen. Open the debugger to single-step the 18-bit CPU, watch AC / IO / PC / OV in octal, set breakpoints on the program counter, and read core memory as octal disassembly.
