Pimp my prommer!

Kustaa Nyholm has a few more components on his board at his Fun with HC08 page which can turn your prommer board into a minimal "development" board. This is very handy if you work on the MCU code and want to try it out without taking the MCU out of the prommer and into your "production" board.

See the "Full schematics" on his web site for more details.
