sit ( StuffIt Expander) or only work with later Mac OS versions. Additionally some third-party fonts are distributed in. This is a shame for me as that’s where the interface started diverging by adding color and some more interesting fonts. While James Friend’s PCE.js puts System 6 and System 7 at your fingertips when it comes to later 7.5, 8 or 9 the site doesn’t have you covered as PCE doesn’t support PowerPC emulation (it handles Motorola 68000 and Intel 8086 processors). One limitation I’ve run into is digging into old Macintosh fonts. I’m often digging into old bitmap font and UX design out of curiosity - and someday hope to revive a lot of these fonts in more modern formats using a pipeline similar to that for ZX Origins so we can get all the usable fonts, screenshots etc.
