40 years ago the IBM PC (Model5150) was introduced. Along through my life, I’ve had occasion to work on a few of these Model T’s of the computer world. It represented state-of-the-art of the day, but is laughable by today’s standards. The CPU was one core running 4.77 Mhz, or about 1000 times slower than just one of our 4,6, 8, or more cores in our systems today. Floppy disks, 16 to 64k of RAM, and it was about $4100 in today’s money for the bare bones version. The printer was dot matrix, and about $13k in todays cash.
