Pot calls Kettle Black
Totally irrelevant screed? You didn't even attempt to answer the OP's question. I apologize for my sarcastic tone, I was having a bad internet day (who really cares that much about Tiger Woods?), but you obviously missed not only my point, but the OP's - not to mention, you contradicted yourself. Zapf Dingbats was not an "original" LaserWriter font,and Symbol was - as you neatly point out in your dubious "quote". By the way, quoting some web site as an "authority" is not
de rigeur, my quote is directly from the Apple LaserWriter manual.
Now, to demonstrate how thoroughly we both missed the OPs point. Though the heading reads "Apple LaserWriter symbol font", the body says he is searching for a font he describes as "included on the floppy with my old LaserWriter was an Apple symbols font", that's not what he is really looking for. In the last sentence, the OP states he "had an 8100", which is, of course, not a LaserWriter, but rather a LaserJet. Apple made an "810" and an "8500", but never an "8100".
So, my informed guess is that he is looking for "Wingdings", which includes clock faces, etc., but I find no glyph of "circle with five horizontal lines". Laserjets of that era came with a 45 TrueType faces for Mac or PC, including Wingdings, and a 65 "SmartFonts", which if I remember correctly, only worked on a PC.
Next time you go off on your own "screed", try to remember why you're here - to answer questions, to help or aid people in finding solutions. Your "screed" does none of these.
with humility,
