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.
