Did anyone buy a kit from Stewart Starbuck?

Hi
I bought a Prusa Mendel kit from Stewart last year and have just replaced the chip to be able to run Marlin. I'm having difficulty configuring it without access to the numbers Stewart downloaded on the old chip. Did anyone else buy a kit from Stewart, and if so, do you know how it was programmed? He may have put a file online for us to refer to, but I've searched Github and can't find one there. Alternatively, does anyone know how to contact Stewart? The details he gave me for email, phone and website no longer work.
Thanks
Jan
