The Amiga 1000 Phoenix Enhanced motherboard

Retrohax.net got their hands on an extremely rare motherboard replacement for the Amiga 1000 - the Amiga 1000 Phoenix Enhanced motherboard. It's difficult to say exactly how many of these were made, but some people claim around 200, while others peg the number at around 2000. Either way, they are rare.

They set around to get it to work, which required a lot of work. There's tons of photos in the article, and you can go to this forum post for another user who came to own one of these rare motherboards for more information.
