However, I have finally managed to lay my hands on a genuine
PostScript printer, and found that the generated fonts did 
not work :-(. I have fixed the bugs in unMac, so here is
the new, improved, unMac version 1.1.

Just to recap (for those who tuned in late), unMac is a PC
program to convert PostScribble fonts in Mac format into 
straight ASCII format. The fonts are stored in the resource
fork of the Mac file, which can be copied off with the 
Dayna `dosmount' utility. This program converts such a 
DOS version of a resource fork into an ASCII file. It works
on a Qume Scripten, with various Adobe (TM) fonts.

   resource containing an Adobe font (whew!) copied with ``dosmount'',
   into something that I can download to a laser printer from anything.
