Peter DiCamillo contributes the following public domain solution:
BitFont is a program which will create a bitmapped font from any font which can be drawn on your Macintosh. In addition to standard bitmapped fonts, it works with Adobe outline fonts when the Adobe Type Manager is installed, and works with TrueType? fonts. BitFont will also tell you how QuickDraw will draw a given font (bitmapped, ATM, or TrueType) and can create a text file describing a font and all its characters.
BitFont was written using MPW C version 3.2. It is in the public domain and may be freely distributed. The distribution files include the source code for BitFont.
Berthold K.P. Horn contributes the following solution.
This is a commercial solution. A font manipulation package from Y&Y includes:
AFMtoPFM, PFMtoAFM, AFMtoTFM, TFMtoAFM, AFMtoSCR, SCRtoAFM, TFMtoMET, PFBtoPFA, PFAtoPFB, MACtoPFA, PFBtoMAC, REENCODE, MODEX, DOWNLOAD, SERIAL, and some other stuff I forget.
To convert PC Type 1 fonts to Macintosh use PFBtoMAC on the outline font itself; then use AFMtoSCR to make the Mac `screen font' (repository of metric info). You may need to use PFMtoAFM to first make AFM file.
To convert Macintosh font to PC Type 1, use MACtoPFA, followed by PFAtoPFB. Then run SCRtoAFM on screen font to make AFM file. Finally, run AFMtoPFM to make Windows font metric file.
Y&Y are the `TeX without BitMaps' people (see ad in TUGboat):
Y&Y makes DVPSONE, DVIWindo, and fonts, for use with TeX mostly, in fully hinted Adobe Type 1 format.

Mac Screen fonts can be constructed from outline fonts using Fontographer, as well.
