PSone celebrates its fifteenth birthday today, as detailed by this splendid SCEJ page.
The machine launches on December 3, 1994 in Japan, and went on to sell over 125 million units.
It took almost a year to get out of Japan, launching in the US on September 9, 2005 and Europe on September 29 in the same year.
What’s left to say? A beast. A boxy, grey beast. Little life-changing man: we salute you.
