My first exposure to computers was in '68 when one of my friends was taking a Fortran course, and he helped me to write a few programs. I would go to the computer center, type it in on a punch card machine and submit the cards to the operator using his account number. I'd go back the next day, had a class in a neighboring building, and pick up the cards and printout. Had a lot of fun doing that.
I bought a TRS-80 Model 1 soon after they came out and wrote a lot of basic programs and did a little assembly programming on it. When the IBM 5150 PC came out, I bought one of those too. In the early '80s I worked for a freight broker and set up PCs for myself and the bookkeeper to use. Software for accounting was pretty pricey back then, so I started writing a couple of A/P and A/R programs, but that was a little over my head. We were able to get a Miles Labs IT guy to help getting it finished, and he took over and completely rewrote it with an ISAM module to manage data files. It worked great and we used it until the owner closed up shop in '91.
Been building, fixing and upgrading PCs ever since. Just built a couple Ryzen Win10 systems for a longtime customer last month. Windows 10 sucks.
