Spice is an "analog" simulator and makes very heavy use of floating- point, so both speed and RAM space would be major issues running on an Apple II.
You could do small problems, like the ones in books about learning to use Spice. Sometimes for real problems one only needs to run Spice on a small part. I haven't looked to see how big it is, though. You might want more than 64K of (bank switched) RAM to use it. -- glen
