Has anyone figured out, done or otherwise documented the maximum amount of maximum RAM on a Mac II Series Mac and with what type of RAM?

I know of one case - MacClassic and his SE/30 having 69Megs using EDO RAM. This is his post:

In theory he could have 128MB of RAM on the SE/30 but did not have enough resources to get it done. Personally I would like to know what is obtainable in theory and what was done in the past by the members.
