That Model D had magnificent typefaces; it was proportionally-spaced.
The space bar was split in the center--one side gave you an "em" space
(wide); the other gave you an "n" space (narrow). When backspacing to

I remember about 30 years ago, a registration card for a Microsoft product

One evening, there was a line of 15 people waiting for a regular punch and a
