SEAC (Standards Eastern Automatic Computer) demonstrated at US NBS in Washington, DC – was the first fully functional stored-program computer in the U.S. May 1950: UK The Pilot ACE computer, with 800 vacuum tubes, and mercury delay lines for its main memory, became operational on 10 May 1950 at the National Physical Laboratory near London.

(The IBM personal computer (PC) and compatibles use processors that are still backward-compatible with the 8086.) Other producers also made microprocessors which were widely used in microcomputers. The following table shows a timeline of significant microprocessor development.

The first mass-produced computer, the IBM 650, also announced in 1953 had about 8.5 kilobytes of drum memory. Magnetic-core memory patented in 1949 [138] with its first usage demonstrated for the Whirlwind computer in August 1953. [139] Commercialization followed quickly.
This had 60 50-bit words of memory in the form of capacitors (with refresh circuits—the first regenerative memory) mounted on two revolving drums. The clock speed was 60 Hz, and an addition took 1 second. For secondary memory it used punched cards, moved around by the user. The holes were not actually punched in the cards, but burned.
The Spectrum sold with two memory options, a 16 KB version for £125 or a 48 KB version for £175. May 1982 US IBM launch the double-sided 320 KB floppy disk drive. July 1982 UK US Timex/Sinclair introduced the first computer touted to cost under $100 marketed in the U.S., the Timex Sinclair 1000. In spite of the flaws in the early versions ...
Networks of such miniature tissues could become functional using stimulus-response training or organoid-computer interfaces – to potentially become "more powerful than silicon-based computing" for a range of tasks – and could also be used for research of various pathophysiologies, brain development, human learning, memory and intelligence ...
