TLDR: Sphere Corporation’s Sphere 1 computer, launched in 1975, was an all-in-one microcomputer that prefigured later mass-market models. Research historian Ben Zotto is documenting its history, seeking materials and stories about this obscure device. Explore the virtual museum and emulator on the Sphere website.
Mike’s website highlights his enthusiasm for vintage computers, mainly Apple models, as well as a variety of tech hobbies. He restores, builds replicas, and operates classic machines, sharing his experiences and advice with the community. Mike believes these old computers should be kept running, not just preserved, and provides information, kits, and resources for other hobbyists. His site also covers related interests like repair tips, history, and new ongoing projects.
Tech critic Benj Edwards argues that personal computing, once a symbol of individual control and creativity, has been undermined by surveillance capitalism and DRM, leading to a loss of autonomy for users. He emphasizes the need to reclaim digital freedoms by advocating for systemic reforms such as privacy legislation, Right to Repair laws, and the repeal of restrictive DRM practices. Edwards believes that personal computing can flourish again, provided society prioritizes user rights and addresses the current exploitative business models of tech companies. The call to action includes supporting open-source projects and fostering a movement towards Personal Computer 2.0, emphasizing that true digital freedom is essential for maintaining personal liberties in today’s interconnected world.

TL;DR: The MOS Technology 6502 microprocessor, influential in computing during the late 1970s and 1980s, emerged from a team frustrated with Motorola’s costly 6800. Developed by ex-Motorola engineers at MOS, it featured innovative NMOS technology and shaped various iconic systems like Apple II and Atari. The manufacturing involved complex photolithography, with emphasis on small die size for cost efficiency. Despite challenges, the 6502’s performance and design laid a foundation for modern computing, with notable steps in transistor-level design and circuit simulation integral to its creation.

Commodore Amiga launched in 1985, designed by Jay Miner after leaving Atari. Initially planned as a game system, it pivoted to a computer due to the industry crash. After financial struggles, Commodore acquired Amiga for $27M. The Amiga 1000, with advanced graphics, launched at a high price, leading to slow initial sales. It saw success with the later, cost-effective Amiga 500 and 2000 models. Despite its innovations, Commodore faced bankruptcy in 1994 amidst industry changes. Comparisons with Atari ST highlight distinct preferences, with the Amiga known for gaming and creative use, while Atari offered lower prices and practicality.
