[Elecraft] OT - Type font question

[Doug Faunt N6TQS +1-510-655-8604]

My recollection was that the slashed letter O was a COBOL thing.

I'd just gotten out of the Navy where I'd learned to slash the number
0, and it was a wrench.

I just looked at one of my 1401 Autocoder books, and it doesn't show
the slashed O (or 0).  Neither does the 7040 MAP book or listing.

   In the late 1960's some IBM system programmers decided to use the solidus
   (slash) through the letter "O" to differentiate it from the simple circle
   that was used for zero at Sylvania's Electronic Defense Laboratories where I
   worked as a writer.
