The problem is this - if you want anything greater than System 7.1.2 to run fast on your 68K machine, you need to remove the PowerPC Fat from the file's coding. It's simple math - if your system is 10MB (like on an LC-Like system) and your System 7.X.Y uses 7.5MB of that, how much is left for programs and data files? It is simply put - with your system and apps running on Virtual memory on the hard drive, if your system allows it, it's going to run slow!
But removing PowerPC Code from the 68K Machine's system will shrink it some 45% - 55%. Now your System 7.X.Y is 3.8MB instead of 7.5MB. On a 10MB LC-Like system, this gives you more room to play with. The same applies to your Apps. Now that they can it in RAM, they can run faster. A lot faster.
And this is true for all systems. In the past I done it for my Plus, IIcx, IIci, LCs and Duo, 190 and 5300 laptops. With the PPC Machines, I stripped out the 68K code. The machines all run fast. And there is room for apps and large files.
