Chris, here's some pics of the disto 1 meg and the layout of the fan and interface

The original 512k upgrade (hemphill) sits on top of an additional 512k board (disto) and the DAT board sits over the 6809 and is soldered to all pins of the 6809 (last pic)
These were taken right before I went throug the whole thing and cleaned everything and reseated all socketed chips.
