So thay are Data General "mostlies". Will they run early Nova code,
before Data General started to expand the architecture?

This is how it is supposed to be, when the AN/ system was laid down in
1942. It obviously does not work.

These machines do not have the gaskets or a fill port. The 1666B has
massive heat sinks on the side, however.
