    Default E682 strange behaviour

    Hi, got a very strange problem with my e682 controller, when powered on ports 1-4 don't come on, if I pull out each connection on those ports and plug back in when its powered on all work fine until it's powered off again. I've tried the fuses and different connectors and also changed the pigtails on those out puts. Any advice would be welcome.
    Thanks

    maybe a bad socketed driver chip, try moving them around to see if the problem moves do a different set of ports

    On 5.03 I think, worked fine at halloween and a few days ago when testing a few things.

    Do the chips you mention pull out or are they soldered in.

    Thanks for your responses.

    One last note about chips. This was a common issue with "EARLY" IBM PCs. Oxidation (primary cause), poor mechanical contact or just simply socket pins that became weak caused problems for socketed chips.

    Occasionally it becomes necessary to "EXERCISE" the socket connector and IC pins. Simply by removing it and putting it back, the pins on the chip and the socket scrape the oxidation off and provide a good contact again. Occasionally a bad socket has to be replaced.

    Most times simple exercise clears up problems.

    Good to hear everything works now.
