With this much talent in the Amiga community I'm stumped as to why no one has created a new mainboard for some of the other Amiga models out there.
I think antigravity was doing something a while back but they were having trouble with their "talent". Or, some stories say, he was having trouble with them. Pretty much it was one guy commissioned to do some kind of clone Amiga or something. Whatever the jargon that applies, it might have been called "boxer", but I'm not sure. I think it only got as far as them showing the unfinished prototype at a few Amiga shows.
