This week is the 21st birthday of the IBM 5150 also called the IBM PC. I know it wasn’t the first personnal computer, there are quite a few contenders for that title, but it was the first computer to call itself a PC. This wonderous machine cost $3,000 came with a massive 4.77Mhz 8088 Intel processor with 16 kilobytes (expandable to 64k) of memory and ran PC DOS 1.0 which was licenced from a man called Bill Gates.
