One byte of ENIAC RAM (circa 1946). Back when a single byte needed an entire rack of vacuum tubes.

IBM 5100, released in 1975 - a 25 kg "portable" computer. Programs were stored on huge cassettes, but the real highlight was the toggle switch: BASIC or APL, selected in hardware.

Casio made plenty of fun calculators, but this boxing-themed one (BG-15) is new to me. Reportedly a hit with school kids in the 80s.

Portable PC design: a full desktop tower + keyboard + monitor. When folded, the screen faced the system unit for protection. A suitcase-sized computer for serious mobility.

In 1980, if you bought a Burroughs B90 for your office, you didn't need a desk - the computer was the desk.
And that "fridge" in the corner? About 200 MB of storage. The entry-level B92 cost a modest five-figure sum, giving you 128 KB of RAM and a COBOL compiler.

The Fairchild Channel F console, released in 1976.
CPU by Robert Noyce, who later co-founded Intel.
RAM: 64 bytes. Graphics: 128×64, 8 colors.
And those controllers? Still look ready for store shelves today.

This is how computer memory was made! New York, 1956. Photo by Ansel Adams. If you also knew how to knit, you could upgrade your RAM yourself!
