I think this is roughly it:
- Magnetic beads manually strung on a thread, each one representing a single bit
- Punch cards/tapes
- Single-line text editors, for use on a teletype (a-la
ed
orqed
- which still somewhat alive assed
) - Multi-line, or “visual” editors, for use on the terminal (a-la
vi
) - Modern IDEs
Sounds like that codebase was truly awful for user privacy then.
