Zorro III memory card... now with Ethernet
There's been some free space on the PCB anyway
First I have tried CS8900 chip, which was great to start with, but later followed Jason's advice and switched to a DM9000B from Davicom. The registers and EEPROM can be read and written just fine, now I'm the proud owner of a network card with 64M of packet buffers... or a network-enabled RAM card, whichever sounds weirdest. Tailoring the (non-working) CS8900 driver for the DM9000 will be another saga. |

Enter card #2 (lower one). Will go to a local amigan who agrees to suffer the consequences of running freshly brewed drivery on top of hand-soldered hardware.

Are you planning on selling this card? If so I can likely get support added for it so it will work with AmigaOS 4.1 Classic. Can you post the showconfig debug output of it?
Thnx |

...and a gfx chip... and a sound chip... and a cpu... and a new motherboard
Seriously, great stuff, like it. Is it hard to make it for ZorroII? would be a cool thing for A2000s... |

Sorry, this particular board has already been reserved. I am going to assemble 2 more boards shortly, PCBs and most of components are on their way. Will be happy to sell them to 'early adopters' for joint testing/bugfixing/development. Luckily there won't be any soldering involved Also, there is no Zorro II support yet. And a few things beg to be improved in future revisions, if there be any. Having IDE onboard would be nice for A3000, right now I have to boot using Buddha or Deneb. For Zorro II, everything has been routed into FPGA, it is a matter of writing some Verilog code and flashing it using cheap USB Blaster dongle (and having A2000 around).

I think the RAM part should work under OS 4.1, it's plain Zorro RAM. Ethernet probably is another story. There's a 3.x driver for DM9000 chip, perhaps OS 4.1 would call for a native one. I don't know how different 4.x is from 3.x. |

Hi Tim,
I'd like to add your card(s) to boards.library - are the product IDs final and do you already have some names for the babies? Kind regards, Marcus |

Marcus, you are certainly welcome. The product IDs won't change (23 for Zorro memory board since 2010 I believe, 24 for the dm9k network card since 2013). There's no fancy names yet, the board is labeled 'z3sdram v1.2'.
If I go for another redesign twist, the result could probably be named something like 'Sputnik' or 'Gagarin', waddaya think? |

I think fancy names are good Amiga tradition.
Do you plan to do hardware mods or just update the sources of the fpga? I'm asking because I'd like to distinguish between prototype boards and later versions. If you want to keep ID 23/24, we could do achieve this through the Autoconfig serial number. |
