Mitch 2 (anode & cathode, 16-ch) [on hand]
Gerard 1 (anode, 16-ch) [assembled, not yet tested]
FDC 4 (anode & 3 cathode, 16-ch) [assembled, not yet tested]
CDC 1 (anode, 16-ch) [assembled, not yet tested]
Interposers:
FJB 2 [on hand]
Mitch 1 [on hand]
Gerard 1 [assembled, not yet tested]
FDC 5 [assembled, not yet tested]
CDC 1 [assembled, not yet tested]
Cables:
FJB 2 (10 ft & 65 ft)
Mitch 1 (10 ft)
FDC 2 (65 ft)
CDC 1 (10 ft)
