why were there 'clone' Amiga's made??? always loved that term in the early 90's..'hey man is that an IBM PC or a clone??'
I presume you mean no clone Amigas?
1. Commodore didn't licence the chipset.
2. Reverse engineering Agnus/Denise/Paula was not cost effective.
Only simple machines have pirated clones usually, like the Hong Kong Apple II machines costing 2/3 to 1/2 the price of the real thing.
PC being cloned never helped IBM's fortunes, Microsoft were the only winners in that situation with DOS/Windows.
