Interesting Amiga Emulation action.

Someone over at Amiga.org _claims_ to have recreated in HDL (Hardware description Language) some of the functionality of the Amiga OCS chipset.

Enough to get some games & Demo's to work.

Here are some pictures of his devkit.

Interestingly he quotes that his source of knowledge on the Amiga chipset was (amongst other things) was the UAE source code.

I'd really like to see this project go opensource, I (as a HDL engineer) could devote some time to it.

ah, great! Can't wait for a Amiga DTV!
(all who own a C64 DTV "C-64 in a Joystick" know what i mean)

I personally hope Dennis doesn't decide at this point to go commercial. If he does, and for whatever reason never completes it, the work will be lost, ala Mick Tinker's work on the BoXer.

You never know, it could become an open source scene project as other Arcade FPGA designs have gone.

The size of the design and the cost of the FPGA's will make it prohibitively expensive unless he can raise the capital to go down the ASIC route.

This project is very interesting and nice to see someone going forth with it.

You think it'll be that cost prohibitive using FPGAs? The Spartan-3 starter kit is around $100. Most users don't need to have development capabilities, which will reduce cost. I imagine Dennis is just doing it as a hobby and doesn't have any current plans to market it.

AlexH -- please let me know if he ever respond to your Verilog debugging inquiry. I'm in the same field of work.

So AlexH is this some kind of hardware card for PC to make it run amiga stuff excuse the lameness but some of us just don't know about these things!

Perhaps in the future Sarek. At the moment he's got a re-programmable chip. He's reverse engineering how the Amiga chips (Gary, Denise, Agnus, Paula) worked and writing them in HDL (hardware description language).

It might be possible in the future to re-create the Amiga in a single chip, at the same time, improve on several limitations (2mbyte chip RAM etc.)

Dennis isnt the only one working on them, but he is the first to release any results.

Yes.

50% margin is what the companies such as QVC will be looking for. For it to go onsale at ~$55 it has to cost ~$25 to make including packaging etc.

It will be on the back of his mind.
