Thread: SCP MS-DOS 2.0 File Transfer program

  1. #1

    Default SCP MS-DOS 2.0 File Transfer program

    I am now ready with my SCP 8086 computer.
    The Morrow HDC/DMA hard disk controller works now perfect.
    The Operating system is SCP MS-DOS 2.0.
    But i have no tool at the moment to transfer files between the old and the modern world.
    The floppy disk format i have available are 8" SD/SS and 8" DD/DS.
    So i am looking for an serial file transfer program to exchange data between the two worlds.
    Any thoughts welcome.

    Well, you can tweak a copy of DSZ or Kermit--the user-configurable overlay is pretty well documented for both.

    Transfer of text via serial port at low speeds using COPY should get you started.

    Hello Chuck,
    Text transfer is no problem over the serial console.
    The binary files are the problem.
    What means "DSZ"?
    I looked at the the early versions of Kermit, but i have to do a lot of programming in 8086 assembler to get it work.

    DSZ = Zmodem.

    If you can transfer text files, then encode your binary files and Intel HEX and use DEBUG to load and save them. It isn't well-documented, but DEBUG does understand HEX files. Just be sure to origin your HEX files at 100H to avoid overwriting the PSP area.

    There are plenty of BIN to HEX programs, here's one running under DOS

    This will work for binary files up to about 64K in length.

    Yes, you'll have to do some programming to get any of the commodity transfer programs to work. That's just the price of ownership.
