Yeah I found 30 pin connectors, need some FFC ribbon for it too, that's also elusive. I want to connect something* to the keyboard port. The Lyra 2 I notice clips onto a chip on the motherboard instead, but there are reasons I don't want to have to do that. Well, because I want also to be able to use it with the Keyrah, which will save me having to design & make my own keyboard controller circuit.
*namely a replacement keyboard I intend to make.
