    Having an issue configuring a MAX232 chip (I know - there's not much to it!)
    I'm using a 7.5V 1A DC plugpack regulated by a 78l05 - 1A

    Chip is configured as per datasheet data

    on a breadboard -

    Pin 2 reads +4.71V (I believe this should be +10V) -

    Pin 6 reads 1.32V... -

    down to 0.73V after a couple of seconds -

    Any ideas?
    Thanks in advance!
