Hannes,
I suppose Monticello could be coaxed into providing suitable data, but I know next to nothing about Monticello or what the procedures were in those days. So, if someone want to make some change sets, I'll merge them in. The logical place to start would be where the old updates faded out. Do one/a few and we'll see what happens.
Cheers,
BobI try to do as soon as Smalltalks 2013 ends.
