As a result of my AVweb columns and some of the groundschools I'm teaching, I have several old books available in reprinted form. They might seem expensive, but they are in full color, just like the originals. Color duplication is expensive, but schematics and diagrams lose a great deal without color. I sell these at my cost, for I don't want tax implications, and I'm just trying to get the information "out there."
All are available at this Web site.
