为了庆賀两个周年纪念在 2019 年的相遇，現在能在 https://unix50.org 在线体驗各个版本的 UNIX 啦。
TACKER: smj (Stephen M. Jones) SUBJECT: preparing for 2019 (unix 50th / sdf 32nd) DATE: 17-Nov-18 17:36:48 HOST: sdf There is a pretty cool alignment of UNIX turning 50 in June of 2019 and SDF reaching its 32nd year on June 16th 2019. To celebrate both, check out https://unix50.org There anyone can spin up a several different versions of old UNIX systems and play around with them. As a perk, you can also do this on the MetaArray by typing 'unix50th'. That has a few extra features such as networking, extra terminals and persistent images if you want to get more serious about things.
