Apple II for intro to microprocessors

One little device family I forgot to mention previously is the MOT 68HC908
family, which apparently is an MCU family that is FLASH programmable, yet
contains a hard-coded ROM monitor. For those of you fellows wishing to get
smart about current generation single-chippers, this might warrant a look.
There are some pretty small pin-count parts in this series, down to 20 pins,
with lots of resources that you can either use or not, without interfering with
your ability, largely, to use the pins as you see fit. Apparently the internal
bus runs at 8 MHz, which is pretty quick, and, in fact, compares favorably with
the low-end flash PIC's. Moreover, it has a pretty conventional architecture
with both multiply and divide instructions.
