Full Summary
At the Low Resource Computing 2026 workshop, participants explored UNIX V4, the earliest complete machine-readable version of UNIX, recently recovered from a 1974 magnetic tape. The workshop featured hands-on coding challenges using the ed text editor and various terminal setups, including physical and telnet connections.
Attendees created user accounts and navigated the system's unique quirks, such as the use of '#' for character deletion instead of backspace. The challenge involved backporting a program from UNIX V7 to V4, which three participants successfully completed.
The event not only educated attendees about early UNIX but also fostered a collaborative environment, with participants sharing insights and solutions. Overall, the workshop was a success, with participants gaining proficiency in UNIX tools and techniques.
