>Terry recommends jumping up to the HC11 for a processor. This is about
ten or
more years old and Motorola is trying to phase them out. I'd jump a little
higher
to the HC12.
The MC68HC812A4 has 4K of on-board EEPROM, 16-bit bus, narrow or wide
expansion to
4M of program. Two UART channels. (One for monitor, one for MIDI?)
An A/D, 1K of RAM, all kinds of I/O. It runs at 16MHz (8MHz bus).

Hi Gene:
Now I feel bad, I did a consulting job for a medical manufacturer last
year, and I chose the HC11 for the product I designed for them. I did the
circuit design, pcb layout, and wrote and debugged the firmware. I had to
buy a rather expensive emulator too. Oh, well.
