Anyone with a deep interest in hardware, and Jay Miner's computer architecture concepts should become a member of the Natami Project:http://www.natami.net
We're designing a next generation Amiga, and there is some very cool stuff going on over there. The machine is now running, implements the Native Amiga Chipset, and is many times more powerful than the last of the Amigas.
The Natami will be an "Alternate Platform", and it will give you a system that is fully backward compatible, while providing the resources to utilize modern computing applications. It has a strong following, and is by no means vaporware. There is a lot of current development work going on, with regard to new Amiga software, and the OS known as "AROS" is a full Open Source re-implementation of AmigaOS, with the flexibility of easy modification & maintenance.
There are now a number of Hardware projects that are Amiga/AmigaOS oriented, however only the Natami implements the native chipset, and is an extension of Jay Miner's vision.
A beautiful thing about all Amigas is the Atari 8-bit emulation, which can use standard 5.25" Atari-formatted disks, with no additional hardware (aside from the drive itself), due to the very flexible disk controller in the system.
I find the Natami project to be a very fascinating place, to hang out & learn & discuss all kinds of tech stuff. There's a lot of really talented engineers & computer scientists there, working in all corners of the globe, to bring the world a New Amiga. In a lot of ways, it really reminds me of when GNU/Linux was first being put together, lots of great camaraderie & work going on toward a common goal.
Despite all odds, and all of the Naysayers who said that "it couldn't be done"... The Amiga is rising from it's grave. A lot of us were left out in the cold when the company folded, and the Amiga was orphaned. A lot of us despise what has happened to computers, in general. The Natami is a chance to build a system, from the ground up, and to address the needs of people like us, who want a great system to hack on.
Part of the beauty of the system is that it is a fully re-configurable computer, implemented via FPGA, which will allow for full system hardware mods that can simply be downloaded directly to the computer. It is a remarkable device, in many ways, and seems to be blazing the trail to the Future of Computing, by utilizing this technology.
Any coders who miss the "old days" should also get involved, because this system is going to let you break free from the endless Windows/Mac/Linux cycle. It is both "a retro platform" & "a new platform", simultaneously.
Hope to see you there!
