[NEW] Commodore 64 Hardware Simulator

Tue, 20 Oct 2026 21:20:25 +0000

c64-hw-sim simulates the motherboards of the Commodore 64 (ASSY 250407) and of the ZX Spectrum 48K (board Issue 3B), pin by pin. You can lift the leg of a chip, short it to ground or to +5V, pull a chip out of its socket, or open a resistor. Then you watch what the machine does: the picture on the monitor, the keyboard, every signal on the board.
