Hey James, I attended the Ohio Institute of Technology (subsequently bought by DeVry) in Columbus from 1974-1976…we trained on the Bi-Tran Six…Texas Instruments hired quite a few of our classmates and I started there in Dallas working/testing Harpoon radar guided. cruise systems. Lits of Navy guys on that orogram. I ended up in sales!To bad dlarue doesn't appear active I wonder if we might have met because I also trained as an Instrumentation Mechanic at Lowery in 1974 - in fact I still basically work the same job except as a contractor at Cape Canaveral for satellite telemetry systems. Some times I use to think the Bi-Tran 6 was something I made up since there appears to be very little data on it.
