My Dad was a mechanic all of his life. He owned his own shop when I was a kid. He taught me everything he knew about cars, trucks and engines in general. I spent 40 years building Diesel Generators. About 20 years ago, I bought my 1st computer, a Kaypro 4. I learned everything I could about that computer and took from there. I am retired now and can't really afford to do everything I'd like to, but I work on computers, buy, sell them, etc. My Dad has been gone now for 38 years, but he would find computers very interesting indeed. He had an eclectic mind.
