The simplest computing devices we use today have more processing capability than the most capable computing systems of yesterday. For example, the VAX 11/780 delivered around 0.5 MIPS in the early 1980s. Compare that to an IBM zEnterprise™ 196 (z196) mainframe of today, which can support well over 52 KMIPS. However, we can learn a lot from early computing history. If you've ever wanted to boot an IBM 1130, PDP-11, or MITS Altair, then the Computer History Simulation Project is just what you've been looking for.
