  The concept of a hybrid readout of a time projection chamber is presented. It
combines a GEM-based amplification and a pad-based anode plane with a pixel
chip as readout electronics. This way, a high granularity enabling to identify
electron clusters from the primary ionisation is achieved as well as
flexibility and large anode coverage. The benefits of this high granularity, in
particular for dE/dx measurements, are outlined and results of a
simulation-based performance study are given. The structure of the first
prototype board is discussed, including adaptions based on a very preliminary
first measurement for a second production towards a proof-of-principle.
