MOSCIA Fixed typo and CNT is no longer automatically set to zero at the end of a phi2 tick.

src/MOSCIA.js

     // If timer B is running, and timer B tracks timer A underflows
     // tick timer B (or, tick it if CNT is positive)
     if (BITM.isOn(cia.__CTB, 0)){
-      let cs = (this.__CTB & 0x60) >> 5;
+      let cs = (cia.__CTB & 0x60) >> 5;
       if (cs === 2 || (cs === 3 && cia.__CNT === 1))
         TimerBTick(cia);
     }
       }
     }
   }
-  cia.__CNT = 0;
+  //cia.__CNT = 0;
