OK, and I doubt someone has a spare 83+ ASIC? I have access to soldering tools so I could experiment...
Actually, I don't need 83+ functionality so much, all I would like is a normal English OS, but full 83+ would be cool too

Direct access to flash chip (avoiding ASIC and hooking it to PC directly) is impossible too? I see you found out the pinouts for Spansion flash we have inside...
