During the 1970s–80s, NASA used state-of-the-art computers from the company Modular Computer Systems. These "MODCOMP" systems were used in processing and controlling the telemetry of many space projects including the Voyager probes, Skylab, as well as the early Space Shuttle launches.
By purchasing one of these chips, you are purchasing a piece of computing and space history. The data that has passed through these components has controlled some of humankind's most ambitious space exploration projects. Chip manufacturers include Texas Instruments, Motorola, early AMD, and more.
The pictures shown may not be the exact chip you'll receive, but it will be very similar. Comes in protective case.
