If you want AmosPro look in the downloads section on
the Amos Factory it has links to Back to the Roots but to get the compiler to work, I would suggest downloading the Amos 1.0 .ADFs and running the upgrade disks until you're all the way up to Amos 2.0 the last version. (Remember that you can hit f12 to swap disk images in WinUAE.)
Also: select the english key mapping even if you're in the US. Otherwise it may not work with your emulator. (This may depend on where you got you're kickstart image, I'm not sure...)
