exxos's Atari, Amiga & retro forum

Wow! What have I done?!

Reading back through the posts, we certainly have some talented hardware engineers here. I had been wondering privately about how viable using a Raspberry Pi + interface board (via GPIO) connected to the parallel port would be, as a rather over powered intelligent ethernet interface and using the strobe/busy lines for data flow direction control and interrupt.

It would, of course, require a driver at the Atari end and code on the Pi.

That's what happens when you give us idea :)

No sure if anybody had time to review this and confirm that I haven't made any glaring mistakes.
If I don't hear anything after the weekend I might order a set of 5 PCB to be distributed to interested users (just the PCB, you'll need to solder the component on them).

Hi Rodolphe,

I didn't check your PCB, but I was having a little round on this yesterday and found your recent tests on this. Any news on your side ?

Hi.
No I haven't had time to do anything recently. I haven't ordered the PCB yet as I still need to re-re-re-check everything.

Here are the eagle files and gerber files if someone want to order some board. I could order some but I'm in USA and most of the people here are in Europe so I would have to send them to Europe after. I will oder a small set of 5 for me so if you're in USA and want the PCB (not assembled.. don't have time :) ) let me know.
As explained in this thread... we hope it'll work there is not guaranty. I also added a jumper to allow to connect the INT0 pin of the RTL to the /IRQ pin of the DMA (via an inverter) in case we can modify the current drivers to use interrupt (should speed up things).
