In 1991, Apple released Macintosh System 7.0. System 7 was too large to work comfortably from a floppy disk so it was the first version of the Macintosh operating system to require a hard drive. It was also the first Apple operating system to be
In 1941, German Konrad Zuse’s Z3 was introduced in Berlin. It was a fully program-operational calculating machine. Konrad Zuse also developed the Z4, the first programmable modern computer, making him the father of the computer. He also wrote the first algorithmic programming language called ‘Plankalkül’.
In 1951, Jay Forrester applied for a patent for magnetic core memory. Until then, large glass electrostatic tubes were used. They were very unreliable, failing every twenty to sixty minutes. Forrester began a search for reliable memory capability. This would lead him to make one

In 1927, German physicist/chemist Manfred Eigen was born. In 1954, Eigen began using a technique to study extremely fast chemical reactions. These reactions lasted only one-thousandth to one-billionth of a second. This technique was called the relaxation technique in reference to the time it takes
In 1979, Radio Shack released TRSDOS 2.3. TRSDOS 2.3 was the final release of Model I TRSDOS, and probably the most widely used version. Despite the prevalence of third-party Model I double-density upgrades, TRSDOS 2.3 was never upgraded to support double-density. Learn more at http://www.trs-80.org/trsdos-model1-versions/
