The central drift chamber in the Mark II detector at the SLAC linear collider has been instrumented with 100 MHz flash-ADCs. Pulse digitization provides particle identification through the measurement of average ionization loss in the chamber. We present the results of a study of system performance and outline the systematic corrections that optimize resolution. The data used are from a short test run at PEP with one third of the FADCs installed, and an extensive cosmic ray sample with the fully instrumented chamber.
