From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm kind of shocked that it's only been 18 years since the last 486 chip was made. It was launched in 1989 and discontinued in 2008, while the original Pentium was launched in 1993 and discontinued in 1999. Hell, the Pentium 4 was discontinued in 2007.
It's quite incredible, and very interesting. I wonder why they continued to produce these CPUs.
Probably for industrial machines.
Yeah, the amount of industrial machinery being controlled by ancient hardware would baffle a lot of people.
For a comparison people might relate to: There are ATMs running twenty year old versions of Windows XP.
There are still ATMs running OS/2 and probably lots of POS systems running DOS.
