I have a number of old Unix artifacts that I value. If I had to pick one (or one set) top one, it would be the complete set of Research Unix manuals, 1/e through 10/e. Other contenders include the AT&T-branded copy of the Lions commentary (with deathstar on the cover), a signed copy of The Unix Programming Environment, several unix-branded plastic containers (not to do with the OS, but bought from a Korean supermarket a few blocks from where I've lived for 30 years), and a plastic-slide Spin Out puzzle from Binary Arts (later ThinkFun but not part of IBM), an educational puzzle/game company founded in the 1980s by Bill Ritchie (Dennis's brother) and his wife Andrea Barthello. (I remember a prototype Spin Out, hand-made of wood, spending some time in the Unix Room.) But far more than any of that, I prize the memories and friendships I've had with fellow Unix people over the decades, particularly (but not exclusively) from my six years as sysadmin-hack in 1127. I'm very disappointed that I won't be at the last-ever USENIX Technical Conference in Boston in a few weeks. A show-and-tell there of prized artifacts sounds like a great idea. I hope those who do make it bring plenty of artifacts and memories to share. Norman Wilson Toronto ON
