I have just had a couple of brief conversations with the people at Proteon about their Revision D Multibus boards, which they have recently been shipping. There is one important change to the board that people should be aware of. In section 3.3.3.3, when adjusting the board to use a 20 bit address bus, you are instructed to remove IC U125. THIS IS WRONG! You do not need to remove this chip; you just need to add the jumper. On Rev. D boards this IC is soldered onto the board (it used to be socketed) and apparently people have been trying to yank it out, thus damaging their boards. Except for this caveat, they assure me that there should be no trouble making the SUN driver work with Rev. D boards....
