    MUON system: 
        survey chamber positions
        re-clean wires in most chambers (using the ZAP technique)
        minor electronics repairs
        install scintillators for studies of "A-stub" MUON triggers
	install test pixel counters, South-A
        stack Pb+Poly shield around N&S low beta quads 
            to measure and reduce backscatter losses 

    CALORIMETER:
        minor electronics repairs 
        some ICD phototube replacements

    TRACKING:
        record cosmic ray alignment data
        disconnect one bad sense wire in FDC South
        install ZCD scintillating fiber detectors (between CAL&CDC)
            for precision z-position calibration

    ONLINE: 
        upgrade D0 cluster to VMS 6.2

    PLANT MAINTENANCE:
        C4 pumphouse maintenance
        Power substation maintenance
        Fix known LCW & ICW leaks
        Improve Level1 trigger drip detector system
        Test Rack Monitor Interfaces

    LUMINOSITY:
	Install scalers and timing cards for 36 bunch operations
