Thread: Zenith Z171, Morrow Pivot II, Osborne Encore - need service manual!

    Default Zenith Z171, Morrow Pivot II, Osborne Encore - need service manual!

    Hi Folks,
    I recently picked up a working Zenith Z-171 aka ZFL-171 aka Morrow Pivot II aka Osborne Encore.

    I'm not having any luck finding a schematic or service manual.

    I did find a pay site that claims to have Zenith Z170 PCSeries Service Guide.

    Does anyone know of a site that has a schematic for any of these machines available for download?

    thanks in advance.

    Hey thank you very much! That is the document I had found traces of but never the original. Much appreciated. Too bad no schematics... maybe this are lost to time.

    I have a small mystery.... the ram backup battery in this thing is .arked MMB-3.6B Motorola. I assume this is a 3.6v nicad. Was hoping it would be listed somewhere as a serviceable part but it's not in the manual. At least I didnt see it.

    Hey Thanks very much. this is the exact file I was looking for. Much appreciated!!! The document lists a reference for the schematics; maybe they are lost to time who knows. Anyhow, up and running now. Had to replace an oddball Nicad marked MMB-3.6B Motorola. At least I think it was a nicad. hard to tell with no schematic.

    Ah there they are. Here is my first Z-171 project - adding a CF card via the system (ISA) bus.

    This card replicates the Lo-tech design (thanks! creds!) but in a form factor that I think is good for the Z-171. Hopefully it will work exactly the same.
