FWIW
I have a Franklin 1000. When I got one of these Apple II mouse
cards, the mouse didn't work it -- (Mousepaint in ProDos).
I had to do some rom tracing to find that the code tried to decide
which model of Apple it was running on; as well as making sure it
was an Apple ROM that it was running on.
I wrote a one page article for Computist, issue 36 Oct 1986,
titled "Mousepaint for non-Apples". It describes the problem and
provides a patch for MP (MousePaint).
Hmmm, reviewing the article now, apparently getting ProDos running
on my Franklin was also a problem -- and fixed.
