Multiple things:
- I didn't even know this board existed and we started of a G3 Accelerator board.
- The board was mostly autorouted, and the beefier power / ground lines didn't help having straight stuff.

Where did you get this ?
Wasn't critisizing! Just curious, lol I saw the board and thought that doesn't look like the one I have. Auto routing always makes a mess of things so that makes a lot of sense.

This is just a board I had laying around from my 6100. I have all kinds of crap in my stash lol

@macuserman Thank you !

Don't worry, I didn't feel you were criticizing. English isn't my first language, my answer was just half stoic half intrigued by your board. It may have been perceived otherwise.

Your board looks like to be 4 layers tho, mine is only two which may explain the routing mess as well. For example, Pin 182 is +5V and isn't routed on the front nor the back. This smells power and ground planes.

2 layers is cheaper to build, although indeed not that pretty.

For getting the board printed here in the USA, who are folks recommending we go to and submit the files from the Github?

@FacnyFreddy You can order boards from www.jlcpcb.com, that's the one most of us use. It's a very simple board to assemble, a couple of resistors, two LEDs and the PDS connector to solder. The repo on GitHub includes the datasheet for the connector too, probably obtainable from Mouser or Digikey (I haven't checked).

@joshc I was browsing the github folder(s) and I am looking for what files I need to send into jlcpcb to get this started.

Also, I see that Mouser has the EDAC 302-182-520-900 (182 pin) connector but not the 302-132-520-201 (132 pin) version.
(I took the time to count the pins on the pics of the original PDS riser and it is 182)
