• Musicalc 1983

    From Terry Raymond@3:770/3 to All on Sunday, February 17, 2019 18:33:44
    Hi all,

    I received tons of .D64 images of older C64 midi Software.
    Right now Im trying out Musicalc written by Waveform in 1983.

    I tried booting from the image no go it loads about halfway and just stops
    and I thought that Musicalc may be copy protected because some copy protection checks and if a copy will probably stop, etc.

    I checked Fast Hackem and Maverick parameters and they don't even list anything under Musicalc, nothing. (parms).

    Would anyone know anything about Waveform protection or a way to try editing disk sectors etc?

    Again I don't have the original of this its just a .d64 image, and BTW
    I use CBM Command to write the disk image back to a real 1541 formatted disk.

    I do have the Maverick V5.4 with a good disk editor if anybody knows how to edit Waveform protection (For my own backups only). :D

    Musicalc has a timer that takes around 2 minutes to load with this .d64 image it only gets as far as 1min 40 seconds and it just stops completely.
    I recognize this as being protected because some protection if it detects the disk is a copy then it will do this and stops like a mule.

    Would a disk scan help anybody to determine what is going on?

    When it comes though to disk editors I dunno Im willing to try though, of course I have the original .d64 and can make another floppy of this, or just use a copy of course if I goof it up, etc.

    Hello, and I'm probably not going to be of much assistance. I do have
    both of those copy programs you mentioned but not the original or a tame
    copy of Musicalc. Given the 1983 date if disk copy protection was being
    used it most likely was via placement of specific errors on one or more
    of the release disk tracks. If the .D64 image really is a snapshot of
    the original disk and you successfully restored it to its original 1541
    form, then you have to find where those error track reads are, what
    errors are expected for a successful load, and use Maverick (or even an
    old one like The Clone Machine) to recreate the errors. Is Musicalc in
    BASIC or machine language (ML). An ML monitor may be useful for
    tracking down where the 1541 error tracks are being read. Probably
    stated the obvious here but best of luck. Sincerely,

    Hello, and I certainly don't won't to insult your intelligence but when
    you tried to load Musicalc did you have a MIDI interface hooked up to
    the C64? Perhaps the load is halting because an interface isn't
    available? Sincerely,
