Zorro III memory card... now with Ethernet

[freqmax]

Regarding networking it seems all driver arhitectures suffers from various bugs:
    * AS225r1 for the A2065 Ethernet uses hardcoded driver.
    * SANA-II suffers from an inefficient buffer handling scheme, lacking proper support for promiscuous and multicast modes.
    * Miami Network Interface (MNI) abandoned without support. And still lacks some Ethernet capabilities.

So making a new bsd socket layer and proper hardware driver abstraction API might be a really good deed. Booting from network is also something that is kind of missing. Btw, did you add 32-bit transfers to speed up things? DMA transfers?

How many layers does your card need? and what was the price to produce just the PCB? (via, tin, laquer, etc options?)

Probably, but who's gonna make it, and who's gonna write driver replacements for all legacy hardware out there?

The important step is to create a infrastructure that others can fill in. Not to do it oneself all the way.

The card has 4 layers, and the price of the first (experimental and express) batch was I'd say decent, something like 50 euro per board. Subsequent batches are of course cheaper. I could lookup exact PCB parameters like copper thickness, track width and via size, why?

Curious for other projects probably involving FPGA, ARM, MIPS etc.

Dunno if Saint Petersburg is local though
