    PTAP2DXF - make paper tapes without a punch

    G'day all,
    This is my first post on IndustryArena, please be kind
    I've written a small open source command line utlity called PTAP2DXF that makes paper tapes without using a tape punch.
    Rather, it generates DXFs for cutting workable 8-level, 5-level and other-level paper tapes using a normal home CNC craft stencil cutting machine, the sort that is generally used for making Xmas and Birthday cards.

    It's mostly directed towards vintage computer enthusiasts who might have a paper tape reader but not a punch, but maybe someone here could find it intreresting.

    You can find it on Github at https://github.com/1944GPW/ptap2dxf

    I've written a 26-page illustrated user manual PDF for it which is in the Documentation folder.
    https://github.com/1944GPW/ptap2dxf/...anual_v1.0.pdf

    For Windows users, I've put a precompiled PTAP2DXF.EXE executable there, if you're not fussed on building it yourself.
    I'ts written in portable C# on .NET Core so it is buildable and runnable on Linux and Mac as well.
    If you try it I'd be interested in any comments, bug reports and so on.
    Thanks and regards,

    Steve Malikoff.

    I am impressed, and wonder why......not a negative wonder .....
    I ran parts with 1" analog mag tape, miles of punched paper and mylar, learned ro read BCD and fix tapes
    Yeah we made parts that went into space that way.

    WOW!!!

    I was going to say "get a hobby" but you have one.

    Now I feel bad throwing away that old tape reader / punch on the Tree CNC machine I rebuilt a few years back.

    Great work.

    Tape length and misreads were the bane of tape,
    imagine 4 spindles 4 parts and a read error. oohhhh s**t
    yes that happened. .
    Clean the reader every shift. Tension arms stretching mylar tapes.
    One job 20 tapes. normal stuff
    We switched to 1/2" mag tape cassettes and 7" floppy's with BCL for B-1 at Rock-et-well.

    Thank goodness for read reliability and unlimited tape length.
