This cute little darb is the IBM 5100 Portable Computer, unleashed on the world in 1975, six years before the machine normally called the IBM PC. The base version, with 16 KB of actual RAM, could be had for about $10,000; fortified with a whole 64 KB, it was about twice as much. I have to admit, I’m pretty impressed with that QIC tape backup.
What’s it worth today? Ask this guy: How to go on YouTube, Facebook or Twitter on a 1977 IBM-5100?
I don’t think I have the heart to tell him. After all, it’s a ten-grand (or more) machine.
