root@nebunix:~$ Apollo DSKY

Era
1960s Apollo Program
Type
Guidance computer interface

Explore a tactile, browser-only educational recreation inspired by the Apollo DSKY — the Display and Keyboard interface astronauts used to communicate with the Apollo Guidance Computer through compact numeric codes.

Created by Dennis Hilk as part of the Interactive Computer Museum.

ENTER DSKY

Open the immersive instrument and try VERB / NOUN interaction manually.

About this exhibit

DSKY means Display and Keyboard. The DSKY was the astronaut-facing interface to the Apollo Guidance Computer; this exhibit recreates selected interface ideas, not the larger guidance computer itself.

What you will try

  • Enter two-digit VERB codes for actions and NOUN codes for the data or object involved.
  • Watch compact PROG, VERB, NOUN and register displays respond to educational simulated commands.
  • See how annunciator lamps communicate activity, operator errors and a controlled alarm demonstration.
  • Learn why limited computing and display resources encouraged terse, disciplined interaction.

Educational context

Astronauts used numeric codes because the interface had only a small keypad, lamps and compact numeric registers. VERB described what to do; NOUN identified the data to display or act on; ENTR confirmed each code.

Recreation notice

This is an original educational recreation using HTML, CSS and JavaScript. It is historically inspired, browser-local and deterministic, but it is not an AGC emulator, not original Apollo software, not a complete mission simulation and not a flight system.

No ROMs, original AGC programs, proprietary assets, backend services or external runtime dependencies are used.
