A short history of retro terminals

Amber and green monochrome monitors aren’t a movie invention — they were real hardware in the 70s and 80s. P3 phosphor glowed amber, P1 glowed green. Amber was considered easier on the eyes, and in parts of Europe it was even the standard for office workstations.

A post with photos

This is a demo post with images. Note that any picture in a post is automatically tinted to match the current theme — press T to switch themes and watch the “photos” change color.

Images live next to the posts in src/content/blog/images/ and are embedded with regular Markdown syntax. Astro optimizes them at build time.

Some hardware trivia

Phosphor	Color	Typical use
P1	Green	Oscilloscopes, VT220
P3	Amber	Office terminals
P4	White	TVs, later CRTs

These screens refreshed slowly and the phosphor was “slow” too: a cursor left a visible trail as it faded. That’s the famous afterglow this template imitates with shadows and animation.

Why it still looks good

Constraints breed style. One color, one font, an 8×16 pixel grid — a design system where it’s hard to make something ugly. That’s why the best fictional terminals look convincing: they follow the rules of real hardware.
