This is the 10pt display version of the "Cream" font as used on the Xerox Alto (particularly in Smalltalk76 and its predecessors; a variant of it may still be used in Smalltalk80). The vector version is much higher resolution. This is the font that directly inspired the Apple "Venice" font, and also appeared as the System/UI font (instead of Chicago) on early Mac prototypes.

System font from the Xerox Alto's Executive manager. Surprisingly proportional width for a terminal.

idk, you know?
