Thirty+ years in software with some hardware work. About 20 twenty languages and a dozen OS's on micros, minis, and mainframes.
The first computer I used was a CDC with 4K of core memory and punched card input. The memory was actual cores suspended on a wire grid. It took up about 12 linear feet of electronic racks.
My first 'PC' was an IMSAI 8080 that came as loose parts and no BIOS.
