This font is called "Cream" and was designed and created by Bob Flegal to look identical on both screens and laser printers.

Well, the CRT on our Alto is pretty old, so the text is a lot worse in person. (That's why I used screenshots instead of photos.) But I think that even with a good monitor, the Smalltalk font would be quirky at best.

I don't know, but I've wondered whether they were trying to signal or encourage (in demos or usage), that this was different, than familiar business computers.

It was the late 70s/early 80s, so a certain amount of twee whimsy was obligatory.

I imagine it would look a lot nicer on a CRT vs rendered in high resolution on a LED display.
