Yes Torrey, I'd be inclined to agree with that. Makes sense to me anyway.
I'm sure you should be able to find more information that would indicate that to be the case (possibly).
I have asked some of the staff I am still in contact with but none of them knew anything.
As I said, I still hope to be able to find details in one of the old UK staff mags (Playtime) as it would be great to confirm.
Glad to be of some help, take care.
