New member here. Was reminiscing about my early career working at Sun Electric at their Harlem & Avondale engineering facility (1978-84) when I stumbled on this forum and thread. Had to join. Started at Sun when they did R&D in a small facility nearby in Niles, IL, and I worked on their VAT-60 development, moving on to specialize in exhaust gas analysis (state I&M equipment such as their Inspector), and an internal low-cost IR bench design that could be used in lieu of more expensive units from IR Industries and Sensors, Inc. for exhaust analysis. From there I went to Alltest, Inc., a startup in Palatine, IL that provided small hand-held micro-controlled automotive diagnostic equipment (remember Brainmaster scan tool?) I designed a 4-gas exhaust analysis module (HC, CO, CO2, O2) sold as an optional add-on for their Alltest Advantage engine analyzer. From there moved to CA with the owner of Alltest when he sold it to start-up Alldata, provider of aftermarket automotive repair information (still going strong as a subsidiary of Autozone since they purchased it in ‘96). Left the automotive aftermarket in 2001, and through a circuitous route am now in IT management at St. Jude Children’s Research Hospital in Memphis.
Have been wrenching on cars, though, since I was 15. Still own a Sun 1018 engine analyzer, which was a prototype 1011 with digital displays instead of meter movements that I saved from the crusher. I’m certain that it’s the only one in existence because they never went into production. Still works well, and use it when working on my son’s ‘69 Chevy 10 pickup. Have a full set of original schematics, and several spare boards (all electronics identical to the 1011 except for the digital display boards). It’s resting on a cabinet that sold with the 2001 Diagnostic Computer, their first fully microprocessor controlled analyzer, which was under development while I was there.
