Zorro III Bus Specifications wanted
Anyone got a copy of it? The link http://www.thule.no/haynie/zorroiii/docs/zorro3.pdf seems to be dead.

If you are REALLY thinking of developing a Zorro III card you'd be better off asking Michael Boemer of E3B. He recently developed the Deneb card and he will know all the idiosyncrasies of the bus not covered in any PDF
The developer of the Prometheus (PCI->Zorro III bridge) guy Adam Kowalczyk is quite chatty on the subject too. |

Not that I am going to design something Zorro3-ish, it is that having 16M in my A3000 is no longer enough - thanks to Deneb which brought networking to it. So I just got curious about how hard it would be to hack a Zorro memory extension. (Besides, this Zorro spec was written by Dave Haynie in such a way I enjoyed reading every page of it!) |

I never understood why Michael Boemer did not include a RAM interface on Deneb!? I'm sure it was discussed several times.
Somewhere there is a reference design for a Zorro III DRAM board by Dave Haynie including schematics and PAL source code. Keep your eyes open for a DKB3128 |

I hate potatos and shirts

Also an up-to-date board will use less components and will be a very low profile or half lenght board.

But it's never going to happen so just buy the DKB3128 and enjoy it.

For 200 quid it makes more sense to get a WarpEngine or some other accelerator. You get more memory and a more number crunching power for the same money.

Here's a (very) simple SDRAM controller implementation for FPGA: http://whoyouvotefor.info/altera_sdram.html. Takes 466 LEs, I've compiled and tested it on my Altera DE1 board.

That's a wishbone interface controller, not exactly suitable for anything other than hooking it up to other FPGA designs. On top of that, Altera makes no 5v compliant FPGA's.
