Here are some screenshots of RISC OS 3, including the anti-aliased fonts [1].
In 1992, on a 640x480 CRT, fonts rendered on RISC OS were excellent. Losing this when I switched to Windows around 1995 was a big step backwards.
NB if viewing on a HiDPI screen, the browser will blur the image at it scales it for the webpage. Instead, look at [2] and zoom the page to 50% -- that's exactly how I remember it, except half the size.
