About SimulatorInterpreter

Hi all

for the demo of Squeak I'm preparing I would like to show the VM can be interprted.

I did the following steps with alex and we are stuck:

- took a 3.6 image - created a mvc project - saved the image named mvc36 - took a 3.6 image - executed (InterpreterSimulator new openOn: 'mvc36.image') test

We did the same with the latest 3.7alpha 5623 - we load VMmaker from SqueakMap 3.6g2

and in both cases we got the following DNU

What did we forget?

Thanks in advance

Stef and Alex
