According to The Register, a PDP-11 minicomputer from the 1980s is still running Unix, and the machine has been made visible to online viewers. The exact setup and location are not detailed in the report, but the fact that a decades-old system continues to operate is a testament to the durability of both the hardware and the Unix operating system.
Unix was designed to be portable and long-lived, and this PDP-11 is a concrete example. While modern systems are far more powerful, the continued operation of such vintage hardware offers a rare, live look at computing history. The Register notes that the machine is now watchable, though it does not specify the exact streaming method.
Because this is a single source, there are no conflicting accounts to compare. The report is consistent in its description of the machine's age and status.
