Hello Cory, Ijaz, Erik and all,

The following changes have been made from suggestion by the indicated person. The schematic has been changed to reflect these changes.

Erik - Change D1 5.1 Vdc zener diode to regular diode.

Ijaz - 9VAC - PWR1 input source added.
     - Added a diode D6 1N4001 and changed U5 7805 to      
       7806 to match 6 VDC battery. 
     - Added a diode D7 1N4148 across reset capacitor C7

Cory - Changed output pin of U6 7809 from +5 to +9 VDC
     - Changed output pin of U2 7909 from -5 to -9 Vdc
     - P1.1 is protected by D1 and D4 1N4148 diodes      
       without any current limiting. The diodes 
       themselves provide the protection because they 
       can survive more current than the source can 
       output. 

Thanks to everyone mentioned and to anyone I may have forgotten.

Thanks,

Charles Bannister
