  • Converting PETSCII to (animated) GIF or (A)PNG

    From Tristan Miller@psychonaut@nothingisreal.com to comp.sys.cbm on Tuesday, June 01, 2021 09:18:26
    From Newsgroup: comp.sys.cbm

    Greetings.

    In the early 1990s I used to run a BBS that hosted many SEQ files
    containing PETSCII graphics, including C64 colour and cursor control
    codes. When the files were transmitted to users at 1200 baud, they
    produced clever and beautiful animations. I'd like to convert these
    animations to a format that can be easily viewed from a modern web browser.

    So does anyone know of a free, preferably command-line tool that will
    convert my PETSCII animations to an animated GIF or APNG? I know I
    could write a simple CBM BASIC program to view the files, run it in
    VICE, capture the emulator output to a video file, extract the
    individual frames with ImageMagick, and then reassemble them into an
    animated GIF using gifsicle. But that's a rather kludgy process that
    requires a lot of manual intervention for each and every file I want to convert; I was hoping there might be some dedicated tool that I could
    just run directly on a given SEQ file and automagically get a GIF or
    APNG as output.

    Regards,
    Tristan

    Do you happen to have an archive of those SEQ files available for download somwhere? They'd be useful to demo/test the PETSCII support in my BBS software (www.synchro.net).

    Thanks,

    No, just what I have on floppies somewhere. I haven't yet gotten around
    to copying them to a modern PC, in part because I don't have one of
    those specially modified drives that would let me read the flip-side of
    a double-sided disk with Kryoflux.

    I recently used the services at https://www.floppydisk.com/ to restore some 30 year old 5.25" floppies. They did a great job.

    If you ever get those SEQ files online, please let me know. Thanks,

    Jim Brain from RetroInovations has what is called a Zoomfloppy device, you install some drivers on your PC and hook this thing up to a USB port and then
    a CBM drive to the zoomfloppy. You can then copy disks to .d64 images. Works great and does a great job getting the disks copied.. That is if you have a Commodore Disk Drive.. If not then the only thing is the Greaseweazel like
    you said....

    Because then the disk spins the wrong way.

    Oh, that's an easy one. Just flip the drive over.

    This is explained in the manual that KryoFlux distributes for its
    specially modified 5.25" drives: http://www.kryoflux.com/download/kf_525modded_manual.pdf See in
    particular the section "About flippy disks" on Page 7.
