I still have mine.  It is a log, log versalog, leather cased aluminum 
with magnifying viewer.

When I was in college, we still used slide rules my freshman year and when one of the dormies got a TI 4 function calculator (with LED display) it was like looking into the future.  I used IBM punch cards when taking Fortran classes.   PCs came out after I had started my first job and used DOS (I still have a Microsoft DOS manual).  My boss only bought one PC for the engineering department because the price was so high and after watching a sales demo he asked me what I thought of the machines.  I told him I could see where everyone in the office should have one and he looked at me like I was crazy.> > Tom (getting older by the day)> #5186> > > > > > -----Original Message-----> From: gow2 <gow2 at rc-tech.net>> To: Jerry Knotts <knottsj at galstar.com>> Cc: detomaso <detomaso at poca.com>; michael <michael at michaelshortt.com>> Sent: Sun, Jan 27, 2013 9:57 am> Subject: Re: [DeTomaso] Optical turn signal control> > > Ironically, last night we were cleaning some shelves in the basement.
