Jupiter Ace, launched in 1982 by Jupiter Cantab Limited, used Forth instead of BASIC, which contributed to its failure despite Forth being technically superior for serious software development. BASIC was popular due to its interactivity and familiarity, making it essential for home computers. The Ace was outdated with only 3KB of RAM and basic graphics, while competitors like the ZX Spectrum offered more memory and color. Forth’s implementation made the Ace unique, but it mainly appealed to Forth enthusiasts. Ultimately, basic user needs were for simple program loading, leading to the Ace’s commercial failure.

USB interface created for Engelbart’s 1968 keyset, part of his “Mother of All Demos.” Engelbart revolutionized computing with innovations like the mouse and GUI, showcasing them at a conference but the keyset was less successful. The author created a modern USB interface for the keyset, detailing technical aspects and challenges. The term “Mother of All Demos” originated from a 1991 Intel presentation, later retroactively applied to Engelbart’s demo. Engelbart’s work faced long-term neglect, but eventually gained recognition, influencing future technology.

“Mainframe” originated from the physical frames of early computers like the IBM 701 (1952). Initially, it referred to the main part of a computer, later evolving to denote a large, powerful computer for transactions. The term’s meaning shifted in the 1970s to differentiate from minicomputers, and definitions transitioned in dictionaries over the decades. IBM was hesitant to use “mainframe” as a marketing term until the mid-1980s, after which the usage surged, peaking in the 1990s before declining. Despite predictions of obsolescence, mainframes persist today, and their terminology continues to evolve.
