The 8 most expensive PCs in computing history
The 8 most expensive PCs in computing history | PCWorld
The Programma (1965) was a kind of supercalculator -- it could add, subtract, multiply, and divide huge numbers. But because it could also load and record programming sequences on magnetic cards, most historians consider it a genuine desktop PC. 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.
