    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Brown out detect is the answer.

    Maybe the power-up timer could help on your grandpa F84. But more than likely, a capacitor between MCLR and gnd will work... have a look to the F84 datasheet. i'm pretty sure they show you some RESET circuit there.

    It's no coincidence why most PIC have a Brown-Out detect feature now

    I usually set both to ON

    I have capacitor.

    The only solution for me is to replace the 16f84a with 16f628a , or to use a MCP100-101
