The numbers 0-9 are doubled, along with period (.), comma (,) and dash
(-). Character spacing is 1/10 inch. I did some checking on HP drum
printers (originally from Data Products and Data Printer Corp), and none
of them went to 160 columns.

An afterthought--it would be useful to list the non-alphanumeric
characters. They were far from standard in the old days and
sometimes you could tell a maker by the character set.
