It should also be mentioned that the people at GM had a lot of input
into the architecture of the 68HC11. This goes a long way in
explaining the goofy (though very functional) structure of the thing.

For cheapness, my fav microcontroller is the 8031. (8051 w/o internal
ROM) I picked up a bunch of these things when they were being sold for
$1.95 each.
