- This is simply not true - at least not for a real Mac Plus and a real Mac
- II. (The performance increase for the Mac II is more on the order of 3-4
- X the speed of a Mac Plus.) Now, it might be true for an Amiga emulation
- of a Mac II (i.e., using Mac II ROMs), especially if you're running at
- anything greater than 1-bit video due to the conversion process necessary
- to convert from the Mac's chunky pixel format to the Amiga's planar one.
- What hardware and software are you running (and in what configurations)
- that you see these results?
