This is a bit off topic. Maybe try avrfreaks.com.

The STK500 manual can be found here:
http://www.atmel.com/dyn/resources/prod_documents/doc1925.pdf

The expansion headers can be used.

Is there a more specific opinion ???....

Is there an external bus at all?

Ah, maybe not. I was making assumptions.
