golf ball printer
     
         the ibm 2741, a slow but letter-quality printing
        device and terminal based on the ibm selectric typewriter.
        the "golf ball" was a little spherical frob bearing reversed
        embossed images of 88 different characters arranged on four
        parallels of latitude; one could change the font by swapping
        in a different golf ball.
     
        this was the technology that enabled apl to use a
        non-ebcdic, non-ascii, and in fact completely non-standard
        character set.  this put it 10 years ahead of its time -
        where it stayed, firmly rooted, for the next 20, until
        character displays gave way to programmable bit-mapped
        devices with the flexibility to support other character sets.
