    Asto please don't confuse me with some genius in component identification. Irving is probably in your best ball park for this one. It was an educated guess with the last one and a power of deduction. Looking at the age of the rest of the components I would not even try to repair this...........There are some limits to when you just have to let go of this stuff. To also put something into perspective i worked in there 900/1800 phone division a very long time ago.

    ...Sorry for making you feel this way. My intentions were not even close to this.
    Well, l can do more reading than writing in the future. Yes, I can do that. Besides, I am not writing in my language.

    Again sorry.

    kind regards

    Asto.

    Just found some sd2 boards tonight, 3 boards, mother board and backplane off a Starmill.
    machine would home and that's all, suspect something on the MB went bad as the axis all moved but gutted it and put everything new in.

    Any idea what these are worth before I bung them on Ebay ?

    cheers

    I have taken the top shield off one driver for the photo but they are all identical.
    the mother board has all the plugs attached to the sockets with some of the cable attached so it can be colour checked.

    I'm guessing the fault lay on the mother board as it would home but after that nothing.

    Hi John-S!

    It is nice I can view the images. Please tell me if your machine was modified ever. In case you are not sure please check the underside(copper side) of the mother board for non factory solder joints or wire bridges.
    And, would you please make these images around 300K so I can tell if the boards are compatible with my Triac?
    In case this image size is not allowed here you can use my address <seaman177@yahoo.com>



    Thanks!

    Hi John S!

    I can pay you 125 Euro for the boards because the motherboard is faulty.
    If my offer is fine with you we can talk about the details. There is my email address in my previous message to you.

    cheers

    Asto, will email you later tonight, on the road at the moment.
    I have taken some more pictures but lost my bloody camera, put it down somewhere and can't find it.

    However no jumper underneath on the mother board but two of the chips have jumper wires on top,
    Drivers look clean both sides.
