     Hi all

     Is it possible to program and reprogram a PIC16c84 in circuit I have
     13 volts & 5 Volts on board for vpp / vss for mclear & diode to
     protect circuit from mclr when going to 13V .?

     (clk & datapins) What resistors are required on the circuit?


     Using the ludipipo RS232 interface to program this device. Are there
     any modifications that are required


     This must have been done some where?

     I have this interface connected to a chipclip with ov + data + clk
     pins

     Any solutions would be  great relief thanks for now.
