Silicon? More like tea-spilling-con
The first microcomputer: The transfluxor-powered Arma Micro Computer from 1962
Before Apple, a 20-pound 1962 machine is stealing the “first computer” crown
TLDR: A newly highlighted 1962 machine is shaking up the story of what counts as the first small computer, proving advanced compact computers existed long before the famous 1970s names. The comment mood is mostly delight, with readers praising Ken Shirriff and enjoying the latest round of “history got rewritten again.”
Tech history just got a messy little plot twist. Ken Shirriff’s blog spotlighted the Arma Micro Computer, a compact computer from 1962 that weighed about 20 pounds and was built for serious jobs like guiding aircraft and spacecraft. In plain English: while most people picture old computers as giant room-filling monsters, this thing was surprisingly small for its time and doing real-world work years before famous early personal machines showed up.
And the community reaction? Honestly, it was less a comment thread and more a history-fan swoon session. The loudest mood by far was pure admiration for Ken’s ability to turn obscure old hardware into must-read drama, with one commenter simply declaring that Ken’s blog is an amazing read. That may sound tame, but it says a lot: readers were treating the post like a treasure hunt, the kind of story that makes people rethink what they “know” about who got there first.
The big underlying hot take is the classic nerd-food fight: what even counts as the “first microcomputer”? Purists would say this 1962 machine doesn’t fit today’s definition because it wasn’t built the modern way, while history buffs are clearly thrilled by the upset. The humor comes from that very chaos: every few years, it feels like some forgotten machine crawls out of the archives to yell, “Actually, I was first.” And readers? They seem absolutely delighted to watch the timeline get flipped upside down.
Key Points
- •The article presents the 1962 Arma Micro Computer as an early compact computer designed for aerospace applications, while noting it does not fit the modern microcomputer definition because it used discrete components.
- •The Arma Micro Computer weighed about 20 pounds, occupied 0.4 cubic feet, and was built for tasks such as navigation, steering, radar, and engine control.
- •It used 22-bit words and a serial architecture that processed one bit at a time, reducing hardware complexity but limiting throughput to about 36,000 operations per second at a 1 MHz clock.
- •The machine had a 19-instruction set that included multiply, divide, and square root, and it supported 120 configurable digital inputs or outputs.
- •The computer was built with silicon transistors and diodes using diode-transistor logic, and its later descendants were deployed in military and aviation systems including Navy vessels, the E-2C Hawkeye, Concorde, and Air Force One.
