Where can I get a replacement for my IO port

Someone tried to jam an ordinary headphone jack in there and ended up splitting the entire jack into pieces, i am unable to connect with the cable i just bought (and was hoping that it might still work but wasn’t expecting much). Where can i buy a new part for it? I can do the soldering myself but just need a new part.

You can find replacement parts on places like Digikey, Aliexpress, and likely even Adafruit or Sparkfun. You’ll have to find a port with the correct footprint of course. If your port is too mutilated to tell, here’s some photos I referred from: top down view and close up. You’ll want a port that is 2.5mm and has 3 conductors and 3 contacts.

I don’t have the dimensions of the original port, however with some quick research, I found this port which looks like it should fit. The only issue is the back contact doesn’t line up with the contacts on the PCB. You can likely just solder a wire from the contact to the PCB however, if you look at some of the sites I provided above then you may be able to find a more suited part.

I was unable to find a replacement, so I took an orthodox approach; I soldered female pin headers to each of the 3 solder pads that the IO port would normally be soldered to and snipped off the end of my link cable, and soldered a male pin header to each of the 3 wires from the link cable.

While this method was a bit hackish and certainly not the prettiest thing in the world, I am now able to connect my ti 83 plus to my computer by simply connecting the 3 female connectors to their corresponding male counterparts.

EDIT: I eventually got the courage to give my calculator the repair it deserved. No more ugly wires coming out of the calculator!
