IBM 650 RAMAC, number 3
Produced by the Department of Education at IBM, this video illustrates the capabilities of the machine called Random Access Method of Accounting and Control (RAMAC). At the time, the machine was revolutionary because it was able to complete three tasks simultaneously - store, process, and report information. RAMAC contained the world’s first disk drive and was the first computer able to keep business records up to date and make them instantly available. Random access memory allowed RAMAC to pluck information from storage without plodding through it sequentially, a development that is essential to the way computers are used today. RAMAC was the first engineering success of the west coast IBM research laboratory that the company established in San Jose in 1952.
