    One of larger clients has a piece-of-junk ancient Proxima projector
    that requires RGB input.

    My laptop can only output VGA flavors and NTSC.

    I believe there's a simple cabling adapter to convert VGA to RGB.

    But the Proxima doesn't use RCA inputs, it's got some bastard
    connector somewhat like VGA but longer.

    Anyone know how to attack this?

    (I should have gotten the model number when I was in Colorado but I
    didn't :-(

  2. The last Proxima projector I saw had a custom connector
    which combined the 15-pin traditional computer video
    (RGBHV, VGA, whatever you want to call it) with a USB
    cable (for the remote-control function) Takes a custom
    cable that has the traditional 15-pin connector and a USB
    connector at the other end. Cable was likely included with
    the projector.

    This customer never uses the projector? Or never uses it
    with computer input? Did they loose the cable?

    Call and get the model number, and all the cable info should
    be here...

    As them if they use a VCR with it. If they do, then hopefully either
    the VCR will have a compatible NTSC input (composite? S-Video?) or you
    can take one along that does and use their lead. Pick the right
    channel on the VCR and you're done.

  4. OK for vacation photos, but trying to squeeze detailed technical
    info through composite (or even Y/C) NTSC video may not cut it.

    It was described as a "piece of junk" projector :) That made me think
    it might be more like a pub/bar TV projector than the kind of thing
    anyone in their right mind would use for a presentation. Anyway, from
    your post it seems it's likely it can take VGA which will, as you say,
    be vastly superior to NTSC.

    I have a PC which serves mostly as a PVR so its only "monitor" is a
    TV. It's truly awful for anything but watching TV. Thank god for
    remote administration!

    They're using it with ThinkPads. I have a 5 year old Vaio.
    Thanks! Good link.

  8. I use a ThinkPad at work and a Viao at home. They both use
    industry-standard 15-pin, "A-shell", D-connectors.
