Editing MX13 SpaceSaver Keyboard (section)

====SSII Controller Board====
[[Image:Ssii-controller.jpeg|thumb|right|200px|IBM SpaceSaver II controller with labeled TrackPoint solder points.]]

The solder connections for wiring up the SSII controller are pictured on the right.
In order to fit the SSII controller in the MX13 case while keeping a low profile, it is necessary to de-solder the tall, female ribbon connectors from the board.
There are two ribbon connectors for the keyboard matrix, one for the external PS/2 mouse input, and one for the TrackPoint stick.
The latter is required to connect to the TrackPoint, although it is necessary to add extension wires between it and the SSII controller (points labeled "To TrackPoint" in the picture) since the TP ribbon does not terminate at the location where the SSII controller board will be positioned inside the MX13.
So make sure not to damage this connector when removing it!
The other connectors can be discarded.
