They are in the
https://github.com/OpenSmalltalk/opensmalltalk-vm/tree/Cog/image/old
directory, but they are the result of a work in progress that was the
incremental bootstrap of Spur.  It would take some work to build a one-step
bootstrap from V3 (old format) to Spur 32-bit.  It is possible, but a fair
amount of work.  We have multiple starting points (various versions of old
format) and a moving target as the end point (OK, the end point could be
some standard Spur release and the user updates from there).

But I still think that the right way is to export one's code as packages
and rebuild.  Most code "just works", but nothing is going to automagically
replace one's use of someObject/nextObject, or the assumption that Float is
the only float class, so the user is still going to have to test their code
carefully.
