I will check out Amiga In a Box for my C= Hardware.
If my memory serves correctly, the terms of use of AmiKit
specify use only under WinUAE.
Yes, a part of the fun of the Amiga OS is taking the time to configure the system to "have it your way" like the old Burger King motto. You can still take AmiKit and tweak it the way you want it. This package makes sure that all the bits and pieces (libraries, helper utilities) are in-place so you can do that quickly without the host of requestor errors when you are missing something.
Amiga Forever is quite nice allowing multiple configurations to be on-file so you can try different settings depending on what mood you are in any particular day.
