I did a trace map of the 128K board from the stock empty pins where the Mux. mounts on my 512K upgrade.

I too was concerned as JDW was that I might cause some damage if I did not flip the right combinations of dips in determining just what pins I actually needed. It appears from this that the two leads I should be concerned with are the red and blue paths coming off the 68K chip itself. Perhaps If I simply disconnect the red or blue, then like a light switch, if I do not send the voltage out, then I don't have to worry about disconnecting the rest of the network.
Confirmation would be appreciated. And, anybody got any idea which is the "out" pin and which is the "in" on the 68K chip if indeed it works that way?
