I was wondering if some of you are using this adapter.

Have a few questions:
- what is the purpose of the top-left box header
- what are the jumper settings on the board

This guy made a msx compatible system and this is a board that does the keyboard bit with a 8255 ppi. (So it's not for using with a real msx, you could but it will conflict with internal one if in the same io port, you could possibly modify the bios to access this from a different address.)
The top left header is for programming the atmel chip.
