Analytical Engine

Boots running a demo card program: it computes a value with the Mill and prints it. The current card walks the card chain along the bottom; the Mill panel shows the ingress/egress axes and the run-up lever; the Store shows the columns (Variables). Use the on-screen keypad (or the physical keys: Space/Enter = step one card, P = start, O = stop, ← / → = wind the card chain, R = reset). Open the debugger to single-step the card reader, set a breakpoint on a card, or watch a Store column for writes.
