I'm resurrecting this because too many recent things are pushing me back in this direction.
First, the Navarone from Vorticon. I now have that and am planning on studying it closely.
Next, Shift838 publishing his 2 port version. I lack the skill and knowledge to create my own PCB design for this project and that is what really holds this up. I can't deal with the prototype and all the wires and connections I made while working on this.
Finally, Yesterday's news with a navarone modification article in it.
I think that article brought me back to a moment of confusion that I don't think cleared itself .
I need to know what the pinouts are if you are physically looking into the cart port of your console.
At first i used the image on the left (below) but was told by someone that is how they are on the mainboard but with the 90 degree adaptor in there ofr cart placement, the pins flip vertically. Then I was told by someone else much later that was incorrect and the diagram shows the actual pins as they appear on the 90 degree adaptor, then reading this article it talks about pin 1 being on the right side but I'm unclear if they are talking about the grom port or looking at the card connector from the grom port's perspective.
I just need to know a definitive answer. If I flip the little door open and look inside my console's cartridge port with a flashlight, what pin is the upper most left pin? This is probably why this project stalled out, I'm not getting the pin assignments correct.
The 2 port is on my todo list to get the PCB tooled then I can build and test. I've been a bit swamped with work and wanting to hammer out the SCART-Genie board.. (sent to Oshpark today to print prototype).
I'm hoping to have some time between now and when I get the SCART-Genie to get it completely layed out and finalized for prototype.
