[COFF] German Z4 User Manual from 1945 found

Nothing to do with UNIX, but a reminder that occasionally long thought lost manuals still pop-up. "Researchers will be able to gain a deeper understanding of what’s considered the world’s oldest surviving (digital) computer after its long-lost user manual was unearthed. The Z4, which was built in 1945, runs on tape, takes up most of a room and needs several people to operate it. The machine now takes residence at the Deutsches Museum in Munich, but it hasn’t been used in quite some time." https://www.engadget.com/oldest-computer-manual-zuse-z4-161214346.html
