    Default Big Problem !

    My friend you have big problem ! I had that error and my FTP was out for 6 month ! Nobody had clue how to fix it, but one man (Serbia, Belgrade) figure out how to solve problem.
    Eprom on your board (i think cont) is lose information, that is because probably weak battery or cold environment (my case), u must reprogram Eprom, u need software for that and that software must be uploded from old Mac and to do so u need machine to be online, but now u cant go online because Serial Error, only solution is to remove eprom from board reprogram and put back on the board. U need software for mac and someone who knows to select write part from that inastaltion to put in eprom. For me it work, i hope that u will finde way to solve problem.

    Now I need to find what is the EPROM that has to be reprogrammed, you have the e-mail technical reprogrammed??
    Because I can reschedule, I have the file, just do not know the EEPROM should be removed and reprogrammed, I think it's 3.
    - Service Manual would be great ....

    I was looking for info about this for you.
    Serial Error is pretty vague, and recommends just restarting because of internal communication errors.
    It could be a firmware issue as Bojan says.
    There are two firmwares, Cont and Scon, and the Cont board firmware varies depending on whether the model is a 3050 or 3050Q (5 sided spin mirror) or if the unit has an online processor or is standalone.
    Some problems. If you ran it on a PowerMac HQRip, life is easy! Otherwise, you need an old beige mac with OS9 or earlier. Then you can use the download program and firmware files.
    Sorry I don't recall the details, but there was a dip switch on the CONT board that would have the 3050 power up in the Forced Download mode. Sometimes if you powered up with the MENU button held, it would also come up in the forced download mode. Sorry though, I might be confusing 3050 with Katana, as they are so similar, but I never heard of having to remove ROMs to reprogram them. Yikes! Hats off to them that they got it working!

    Try to re-seat the eproms on the CONT and SCON boards to make sure connections are ok.

    If you have another 3050 nearby try swapping the boards out to see which is faulty.

    I have CONT A v151A and 151S and SCON v260D with downloader program from years ago. You used to be able to get it from Download:MEDIA AND PRECISION TECHNOLOGY COMPANYY but is no longer available.
