Xpantastic!

Hi Jeremy,

Sorry, I may have jumped to the wrong conclusion there. Thanks for the clarification.

Structured assembly language would be very useful. Does your decompiler handle 6809 already? It would be fun to run it against the OS binaries we already have, and start with the I/O addresses to get an initial idea of the complexity of the firmware.

Cheers,

John :^P

But I'm just guessing here, so I'd be interested to hear your thoughts.
