Olin and I used to hang around a lot together at BARH (the residence hall he speaks of for sophmore year). We were bad news. :-) He was very proud that he made _every_ dean's list... including the "on probation" ones. .... and I think I still have that old neon sign transformer. They never die. We also came up with a way to do fast audio A/D using CMOS switches and a bunch of resistors. This was after we blew up the Chem department's PDP-15 by wiring an R-2R ladder to the disk drive controller's track servoing. And then there were the laundry tickets. That was his schtick but he borrowed my micrometer to make it happen. Remind him of that. I still have that micrometer, too. NSK made good stuff cheap then. ---- And, Davo remembers you, too.
