Fascinating discussion. One of my 'fest finds long ago was a 10811 on a 05328-20027 board. When I recently went and googled on that, I came up with a 5+year old discussion from the archives of this very list. http://www.febo.com/pipermail/time-nuts/2005-May/018382.html says that the 05328-20027 goes in a 5328. Oddly enough, the 5328 I have has a 10811 plugged directly into the motherboard so the two must be at least pin compatible. Any opinions on using the 10811 alone or should I put the 05328-20027 in as well?
