Zorro III Bus Specifications wanted

tnt23 · 10 November 2009, 14:57

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

Have a look on this page.

Thanks Dave!

You're welcome.

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.

I got it once, but seems to be wobbly.

Indeed, Michael Boemer is perhaps the best guy to ask about Zorro stuff. I contacted him when I got issues with my Deneb and USB stick booting, and have had a nice talk. However, I'd like to read the docs first to save him a great deal of stupid questions from me

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!)

alexh · 10 November 2009, 22:21

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

Wow, that'd be great to grab!

As I remember it was called BIGRAM

I dont know your config, but this could help.

Be cheaper to buy one of these

With 200 pounds I will have to make up my mind. Definitely trying to mimic BigRam design or to hack my own could be more fun at the same price.

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

I agree with rkauer. Personally, I will go with some 64 MB SDRAM chips directly soldered on the PCB.
Maybe get 512 MB with 8 chips on one small card

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.

tnt23 · 30 November 2009, 10:26

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.
