    Might actually fit some times, but in this case, I think writing files to a second floppy drive while the software is running is likely impossible due to the funky things the software does. On top of that, the software already knows that so it will not give that option in the first place.

    Peter z80, Just plop an XT-IDE in the system and solve all your problems. (is there a free ISA slot?).

    A couple of other possibilities, if you want to do things the hard way, might include some kind of network drive, or a very large EMS card with a ramdisk.

    A transcopy image of a DSDD 360K disk is roughly 1MB, so you will need a larger storage solution as previously mentioned. Hard drive, XT-IDE, ZIP drive, etc.

    Most transcopy images floating around were made with the last version of the software. Images are not compatible between the Deluxe OB and the original OB, and the newest software only worked with the DOB, so hopefully you have a DOB.

    Software and documentation here:
    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)
