RAMAC system in action

A RAMAC system in action. Computer programmers who worked in that era have fond memories of these systems. "I remember the RAMAC maintenance crew used to stand by and plug in new tubes, because the heat and use would blow them suckers out all day long. It was an adventure to watch the control arm move up and down the disk system. It moved at a speed that you could see--amazing," wrote one News.com reader.
