    I have been using an OEM BS2 (kit form) and recently made a connection
    error and fear I have permanently damaged the "stamp".I connected a new
    9-volt battery (my analog multi-meter later measured approximately 8.4
    volts) to the VDD and the VSS pins instead of the Vin and VSS pins of the
    board. In effect I bypassed the voltage regulator and applied 9 volts
    directly to the components on the board.
    Since then when I try to download a program I get an "Error hardware not
    found" message on my monitor. I am using a 386-SX16-computer running MS-DOS
    4.01, which seems to be functioning properly (I had no problems up until
    this point). I tried to program the stamp with a Compaq Presario running in
    MS-DOS mode and receive the same error message.
    Is it possible I have only damaged peripheral components, which I can
    replace, or might I have damaged the PIC chip beyond repair? Any help you
    can give me would be greatly appreciated. If it is possible I have only
    damaged peripheral components a diagnostic schedule to follow to isolate the
    problem would be great. Thanks.
