Thanks for your message. We are glad you like Monaco. We like it too, and once hoped Apple would release a full 4-style family of Monaco, and the same for New York and Geneva. After those faces were launched with System 7 in 1991, we urged Apple to have us design the companion styles to make them full families, but Apple never did. Those faces have huge x-heights, around 54.5% of the body size, and some users preferred Geneva to Helvetica because it looked bigger on screen. This was a consequence of Susan Kare's constructing the fonts directly on the screen and making the x-heights taller than what standard printing types would have if mapped directly to screen. Back then, Apple wasn't crediting Susan Kare as the designer of the original bitmaps, so her name was left out. Subsequently, we always try to credit Susan Kare for her original work on the bitmaps We wrote an article about the design of those fonts and you can find it online. Try the url below.
