I suggest asking over at cosmacelf.com.  There is a lot of Cosmac info and expertise there, not just about Elfs (elves?).
One thing that comes to mind is a series of boards and kits that were developed by a Canadian user group that sounds much like you describe.  Development of those were tracked in their newsletter, Ipso Facto:

Some of the people who developed those systems are members of the forum at cosmacelf.com.
