Apollo Logic Module
This is the type of computer that went to the moon in the Apollo missions
from 1969 to 1972.
There was one computer in the Lunar Excursion Module (LEM) and one the
mothership (CM) circling above.
It was the first use of integrated circuits, as still displayed in the
timeline cabinet to the left. It's cycle time was 1 Mhz, 11 instructions.
It had 1K of 16 bit words of erasable (RAM) core memory and 12K
of read-only memory (ROM). The ROM held the "Colossus 249" flight control
software. There were no disks or tapes in the flight system.
