Probably it was designed - well designed, it sounds like - to handle its
intended type of image: fairly clean black-on-white text.  If this is as old
as I suspect it might be, then one design constraint may have been what now
would seem like a really teeny ROM & RAM budget.  And the more something is
optimized for one specific environment, the less well it does in others,
sometimes even ones not greatly different from its home.  There's a name for
this that comes from biology, but obviously it's a pretty general principle.

In light of today's sad news, I would like to suggest a few quiet minutes in
memory of Dijkstra: spend them contemplating how this relates to Knuth's
famous complaint that premature optimization is at the root of much that
goes wrong in programming.
