Just out of interest, what are the differences between clone-a and chameleon, if both can emulate an amiga?

Mark

From what I've seen in various discussions:

Chameleon is a board, and I believe has a port of the Minimig core, and Minimig is somehow derived from WinUAE. Terasic DE1 is another board with a Minimig core ported to it. The original "Minimig board" is also "just an FPGA board", which of course had the Minimig core inside.

Clone-A is based on Jens and Co. doing lots with a logic analyzer on actual Amiga chips, and presumably would have more exact timing matching between components (between parts of the core). It sounds like he also put undefined/illegal values into real chip registers to see what happened and probably tries to clone those results as well.

They are different implementations toward the same overall goal. Kindof like Phase 5 and GVP both made 68040 CPU accelerators, but they were not identical products in every detail.

aoOCS is a third such thing to compare Minimig and CloneA cores to.

MiniMig has nothing at all to do with WinUAE.

Also, because Winuae and Winfellow already exist, I have the luxury of being able to look how they did it when I'm stuck. (which I did on some occasions)

OK, maybe the 6 years since his post have exaggerated my memory of how much he based his design on how UAE did things, but he did use UAE as a reference to some degree.

MInimig has a real 68k cpu


The Terasic DE1/DE2 port of the Minimig core does not.
