In August 1981 we had a persistent problem with the RP06 on our PDP-11/70 crashing disks. It even crashed once while the DEC repairman was standing next to it trying to figure out why the previous pack had died. We collected a few dead packs, and they were forming a pile. Lillian, never one to miss an opportunity, suggested building a mobile. ...
Or maybe we did it ourselves and Lillian added to it. I remember a foot-across ball of 9-track tape she supplied, but I can't find the photo I thought I had. There's a DECtape hanging here though.
Lab alumni might recognize the top element as the legendary copper-tellurium bar. Everyone should recognize young Dennis Ritchie at the left, leaning on a Tektronix 4014. ...
@robpike if you got time to lean you got time to clean, Ritchie
