Cartridge slot? #18

Open burntbyhellfire opened 1 year ago

burntbyhellfire commented 1 year ago

Getting a 60-pin card edge connector for the Famicom is pretty easy, and I have a few. The Sipeed Tang has enough GPIOs that it should be able to handle it. Has anyone considered an option of building something like this with a proper cartridge connector and controller ports? I wouldn't be opposed to designing a PCB myself for the tang to connect into that can make full use of a new PCB designed to fit the standard Famicom motherboard footprint for original shell compatibility.

Absolutely agreed!

Very interested in this.

The nano 20k does not have enough pins for this. I count roughly 40 pins including the RGB-LCD socket.

Tang Primer 20K has enough pins. But it does not have SDRAM.

There's a GW5A-based nano coming. We can look at that once it comes out.

Would it be possible to do a 20k primer version of the tang? I assume since it has enough pins we could have the cartridge but would have to give up rom loading from SDRAM. (or maybe sdram could be added to a board) Could be worth pursuing for some users. I would love to make board for a version like this.

I also ordered a Tang Mega 138k to hopefully try with as well.

There's also an upcoming primer 25k SoM. https://wiki.sipeed.com/hardware/zh/tang/tang-primer-25k/primer-25k.html (seems the English page is not up yet)

@muramasatheninja what is the best way to DM you or email? I'd like to discuss the board idea.
