| Its memory wasn't made of magnetic cores or semiconductors. Text was first punched into player piano-like rolls with a typewriter/perforator. As the rolls passed over slots in a bar in this machine, a valve opened and negative pressure in a hose collapsed a small bellows that pulled down the typewriter key.
