The graphics could be transferred to a TS1 slotmachine, yes, which is what I imagine S1ndle will do when he is ready. But that object, like many others cannot be used as-is.
The fact that TS1 and TSO/FreeSO objects are not necessarily interchangeable is an important factor that people don't always realize on their own, so I used this opportunity to point it out. It helps them think of things in a slightly different way which invariably helps with future projects (or gives them a clearer picture of some of what is involved which can sometimes let some people know that this isn't the sort of hobby that want to bother with).
