The image used for the book is very old and does not have the cog related patches...

The easiest would be to make a one-click with old vms for the book. Or we would need to find out (remember) exactly which patch is needed...

I guess there is something specific in the Pharo tracker, but there is also: http://squeakvm.org/cgi-bin/viewcvs.cgi/branches/Cog/image/NecessaryImageCha...

Kind of related to that: does anyone have a Squeak 3.9 image running on top of Cog? As far as I understand, the main issue is that the image needs to use Closures instead of old style blocks. Is that correct?

Yes. Would be quite some work, I think. Not impossible, but the question is if it would not be easier to change Pharo or current Squeak (in case of MVC) for your needs. Marcus -- Marcus Denker -- http://marcusdenker.de
