Current (recycler) timing/trigger system appears to be sufficient for TeV BPMs - add injection event to beam sync - TSG FPGAs nearly full, but dropping MDAT decoder and 2 of 6 gates frees ~30% space - could run TSGs at 7.5MHz (instead of 53) - IP Digital I/O board can drive BLM ext dev bus and calibration
