Although it is an honor to be crossed with such a distinguished gentleman (University of Florida professor, many great books on WWII), it's not so. Check his bio on Wikipedia and there is no mention of Workbench Guide to Semiconductor Circuits and Projects. Check the back cover of the book and there is no mention of a Florida professor. I think our names got accidently crossed some time back and the mistake was never resolved. Oh well, it is the electronic age. All the best, (Henry) Michael Gannon, the "real" me.
