Where Can I Find Replacement 5200 Controller Ports?

@aslbozz you could check with console5.com or best-electronics-ca.com and see if they have those ports. It is unlikely given the low production rate of this console. The connectors itself are simple DB-15 connector and you can find those at digikey.com and mouser.com as well as many others. The only issue here will be, that you really have to dig for something that matches your console. It's not as easy as just selecting a direct replacement, but it should definitely be possible. Measure the dimensions of your ports and armed with those measurement, start scour those sites.
