Apple II

I know most games don't fully use the analog nature of the Apple joystick.  But at least one game does (Conan - you can either walk or run) and its not working right on my IIe with two different joysticks.  Anytime I try to run right by pushing the joystick all the way, he never goes faster than walk speed.  Which actually makes the first level impossible, as you have to jump a gap with a running start.  I have 2 different Apple brand joysticks, and neither work right with the IIe and Conan.  They do however work fine with Conan and my IIc and IIgs.

So I do have two Super Serial Cards (1 Apple, 1 Clone), but I also have these and I was curious what I can do with them?

I recently came across the 13 sector ROMs for a Disk II Controller Card and thought I'd give them a try.  But before I do, I wanted to know if a 13 and 16 sector card can peacefully coexist on the same computer?  Or would I need to designate a separate machine? (not my preferred solution since there's not as much out there in the way of 13 sector software)

 Obviously, the 13 sector ROMs would be on different a card than the 16 sectors and in different slots.  So I think it should work?  But I want to be sure before I risk frying something.
