Discontinuation of APV25 and demands on flexibility concerning e.g. detector capacitance and readout rate induced a replacement of the ASIC, for which the collaboration has chosen the VMM chip of the ATLAS New Small Wheel upgrade. A prototype SRS VMM system was operated with small GEM detectors at test beams and hardware components are finalised. More than twelve groups signed as primary system users. We present the readout chain and current status of the implementation of the VMM in SRS, applications and further developments.
