+ProDOS has a built-in clock driver that queries a clock/calendar card for the date and time. 
+After the routine stores that information in the ProDOS Global Page ($BF90-$BF93),
+either ProDOS or your own application programs can use it. See Figure 6-1.

+ProDOS recognizes a clock card if the following bytes are present in
+the Cn00 ROM:
+
+$Cn00 = $08
+$Cn02 = $28
+$Cn04 = $58
+$Cn06 = $70
+
+The address is preceded by a $4C (JMP) if a clock card is recognized,
+or by a $60 (RTS) if not.
+
+The ProDOS clock driver uses the following addresses for its I/O to the
+clock:
+
+Cn08 - READ entry point
+Cn0B - WRITE entry point
+
+The accumulator is loaded with an #A3 before the JSR to the WRITE
