The MITS Altair, the first commercially successful microprocessor kit, was featured on the cover of Popular Electronics magazine in January 1975. It was the world's first mass-produced personal computer kit, as well as the first computer to use an Intel 8080 processor. It was a commercial success with 10,000 Altairs being shipped.
The cassette tape was a common low-cost and low-performance mass storage device for a generation of home computers. Home computers were a class of microcomputer that existed from 1977 to about 1995. During this time it made economic sense for manufacturers to make microcomputers aimed at the home user.
The first computer to use magnetic tape. EDVAC could have new programs loaded from the tape. Proposed by John von Neumann, it was installed at the Institute for Advance Study, Princeton University, Princeton, New Jersey, US. 1951: Australia CSIRAC used to play music – the first time a computer was used as a musical instrument. 1951: US
Whether it’s a first-generation iPod or a retro gaming console (looking at you, Game Boy), here are 10 outdated devices that fetch impressive prices. 1. First-Generation iPhone
