In the process of creating MSFonts, I determined that Windows 95 used a very simple method for creating boldface variants of bitmap fonts: it logically widens glyphs by one pixel and double-strikes each glyph with a 1-pixel offset. MSFonts includes pre-baked bold variants for every font that makes sense, but it isn't too hard to do this yourself for any font that exists in a deck.

You might have luck with bdf-macfonts, which includes TTF conversions of the original 6. Everything I draw here in a classic-mac style is made with Decker, which includes a handful of bitmap fonts closely resembling Geneva, Chicago, and Monaco in its own internal format that I hand-converted.
I have updated my retro-pixel bitmap fonts!
