    I don't really have the space for a proper CRT, and I must confess I rather like using this vintage machine on a modern huge screen (playing Mattel's Night Stalker on a 65" is rather satisfying )

    Edit: I also have an Olivetti M24 with its original monochrome monitor for a proper period-accurate experience.

    Indeed, that is its bread and butter, as that is VGA text mode when DOS boots. But it will drop 1 frame every 7 to fit 70Hz to 59.94Hz (there's no option to blend frames across time or anything; for that, you'd need an old broadcast scan converter like the Sony DSC-1024, although blending across time is a different set of problems).
    Offering a bounty for:
    - The software "Overhead Express" (doesn't have to be original, can be a copy)
    - A working Sanyo MBC-775, Olivetti M24, or Logabax 1600
    - Documentation and original disks for: Panasonic Sr. Partner, Zenith Z-160 series
    - Music Construction Set, IBM Music Feature edition (has red sticker on front stating IBM Music Feature)

    Scitech Display Doctor 5.3 is supposed to contain a utility called "UniCenter", which I presume is used for centering the screen in DOS, at least according to the documentation. That might also be worth looking into.
