Mario Wolczko produced something like this years ago - with some bug
fixes, since IIRC there was one place where a 17 bit cpu was needed -
and you might find files somewhere. You'll need to google both the
correct spelling 'wolczko' and a wrong one 'wolzcko' to get info.

Well it would be pretty much an essential part of the whole thing so
I think you can be fairly confident that Mario's file(s) would have
it. An interpreter without the object memory stuff would be as much
use as a chocolate teacup...
To make any use of it you'd have to also create or obtain an image
file of the correct format along with the sources and changes files.
The bluebook object memory format is very different to the squeak
format.
