The relevant issue is not width of data path, which is utterly unimportant
except for performance, but width of address bus. The PC address bus is
20 bits. On the 68000 machines, it's 24 (more or less, depending on the
implementation). The problem is fitting formatters into 16 bits of code
plus 16 bits of data (to be generous about it): troff, even ditroff, will,
and TeX won't.
