On this day in tech history, An Wang filed a patent which would become the basis of magnetic core memory. After receiving his PhD in applied physics, Wang began working at the Harvard Computation ...

Throughout the history of computers, one aspect has plagued and restricted its growth more than any other: permanent storage. From the very first computers that used punched cards and tape for input ...

This iteration of Electronic Design: Now and Then was inspired when I was reading "Using Magnetic Cores in Computers" from our archives. This article was originally published in Electronic Design ...

Hard disk drives sure have come a long way, baby. In the 1950s, storage hardware was measured in feet—and in tons. Back then, the era’s state-of-the-art computer drive was found in IBM’s RAMAC 305; it ...

Many Hackaday readers will be familiar with the term “core memory”, likely thanks to its close association with the Apollo Guidance Computer. But knowing that the technology existed at one point and ...
