I have Pagestream 4 (68k) running nice and stably on my MOS 3.9 system (MacMini G4). I can display the various sets of fonts installed, with the exception of the Intellifonts within the Pagestream directory (Triumvirate, Times, Garamond). I have a sneaking suspicion these are going to be most useful, workhorse fonts. The others are all large, blocky and look like they're from a 90s PD disk. Not really useful for any real DTP work. I've tried removing and reloading the directory via System Preferences / Fonts but that didn't have an effect.
