Betcha that board can be made for 400USD instead of 400GBP!
Nope. I guess it would cost nearly double the price of the current Troica board.
Belive me, those guys arent stupid, if this could be realised for such a low price they sure would have done this.
It might be hard to accept for some people, but this is about the pricetag that is attached to any homebrew motherboard projekt. There will be absolute no cheaper Amigamotherboard made in many years to come, if you don`t go into the direction of massproduced embedded systems that run OS4 "by accident" but only have about the CPU power of an old CSPPC.
