The JP1 and JP2 jumpers are not present\nin the original schematics but I have traced\nthem on my board. They are labeled "D1" and\n"D2", I have renamed them to avoid conflicts\nwith the diodes bearing the same labels.\n\nTheir purpose seems to be able to enable the\njoysticks after passing through the keyboard\ndriver. Since it seems  the latter was introduced\nlate in the x264 architecture, maybe the\ndesigners weren't sure what was best and kept\nboth possibilities.

This was one of the weakest spots of the C16, where the\nTED chip pins were directly exposed outside through the\njoystick ports.\n\nAdding a buffer will protect the TED from ESD, and TVS\ndiodes could do even more. This is basically Levente\nHársfalvi's design integrated into the C16. Please see:\nhttp://www.zimmers.net/anonftp/pub/cbm/documents/projects/interfaces/plus4joy/plus4joy.html\n\nWe can also consider to replace the MiniDIN-8 ports with\nD-SUB 9 ones.
