Susan Kare defined the look of the Mac with her monochrome icons and set of bitmap fonts. While the Mac moved on Monaco remained a hit with developers and it evolved into a scalable TrueType version with embedded original bitmaps with the help of Kris Holmes. Apple later toyed briefly with Deja Vu mono creating a tweaked version called Menlo before going all-in with SF Mono but Monaco had a good run.
I’m not sure when I created the Spectrum version of Monaco 9pt - it’s been on my drive for quite some time. As it is very very consistent with the original I’ve even debated whether to have this and some of the other similar ones here. I’ll probably move these almost pixel-for-pixel “ports” over to a different label in the future and keep ZX Origins for my own creations and interpretations.
This font works well for titles and large blocks of text and is very pleasing to read.
