As Gordon Bell, father of the minicomputer at DEC has often noted: The most reliable components are the ones you leave out.. The Apollo Guidance Computer program was a landmark both in terms of hardware design and software management and laid the foundation for SpaceLab and Shuttle computer systems development.
NASA purchased several of the machines to plan the Apollo 11 moon landing. Each device cost about $3,500 ($24,000 today), making it easily the most expensive PC of its time -- considering it was the only PC of its time. About the size of a small suitcase and weighing in at 55 pounds, the IBM 5100 Portable Computer was marketed at the time as the world's first mini-computer.
