Well, the LC, LC II and Color Classic run on a 16MHz CPU with no FPU and at max 10 megs of RAM. The closest thing to this to any other Mac is a Mac IIcx at 16 megs of RAM. This within itself is an excellent set up for a lot of things including a few games and other programs. But running FreeHand/Illustrator, its going to be slow without an FPU and the results not perfect as you would expect.
Another area not touched here which also involves these same machines - Photoshop and other Image Processing Software. Though many of them do not require an FPU like PhotoShop, they do require a minimum of at least 16bit (Thousands of Colors) video. 256 Colors is not enough to do good image processing and limits you to a certain numbers of color pallet, at best, you will dither and jaggie your image. At least with the LC, LC II and Color Classic, you can expand the VRAM to get Thousands of colors. With many other Macs, you need to buy a video card that can do 16 bit video. (Fortunately for me, I bought 24 bit video cards long ago.)
