CMBS, DUCT, ELEC, ENEC, FANS, GEAR, HIT.TR, HVAC, HYDM, PCYCL, SCRW, SPIN, WELD, AIR, PSYCH, SAT.T, SAT.P, SUPHT

The program names definitely suggest HVAC. It sure looks to me like something the Ford HVAC group might have produced internally in a small quantity for the use of their own engineers. Since no stickers / labeling on the card itself, it likely wasn't a commercial product. I was a GM engineer for many years (and still work in the industry) and this wouldn't surprise me based on the way we worked. An internal instrumentation group would write collections of special software tools for individual functional groups based on their specific needs. In this case, rather than for a PC, they did it for a common calculator used by (and probably issued to) the HVAC guys—probably it's a EEPROM card. Maybe they made a half dozen to a couple dozen of these, but that's just a guess.

I will add, that it surprised me a little that the guy's business card said "Powertrain Operations". I work on powertrain stuff myself but the program names here scream "HVAC" to me. But maybe he switched jobs within Ford. You might be able to find him online and send an email :-)
