- It _is_ a normal 6809. It is the 2 MHz version with external clock generation
- and a plastic package.

- There are probably some suffixes I don't know about or don't remember (such
- as the suffix for ceramic), but this should be enough. The Motorola data

- One of the places you'd be likely to find a 68B09EP is a CoCo III.
