All the parts

Like a construction-kit manual — all the parts of the three-screen machine. Each bag is the same machine taken apart down to its own level, so the bags do not add up: transistors sit inside gates, gates inside adders, adders inside multipliers.

Bag 1

Transistors and resistors

The whole machine down to the bottom: 106,610 transistors and the 9 ROM resistors.
