Having already introduced the DDI-1<\/a> and the DDI-1 2014<\/a>, there is now news regarding floppy disk hardware and the Schneider CPC<\/em>. Just like the DDI-1 2014<\/em>, this new interface was designed by the versatile developer Zaxon<\/em>.<\/p>\n\n\n\n

The DDI3<\/em> is a combination of DDI-1<\/em> and HXC interface<\/em>. To use floppy disks on the CPC464<\/em>, a DDI-1 interface<\/em> and an FD1 drive were previously required. However, the DDI-1 is difficult to obtain, and\u2014in addition\u2014either a compatible floppy drive or an HXC unit is needed as a substitute. This hurdle is now a thing of the past \u2013 the DDI3<\/em> can replace all of that (you only need a USB stick for the data).<\/p>\n\n\n\n

While this interface is not the smallest device, it impresses with its well-thought-out design. It features several buttons and switches, an LCD for simplified navigation, and a port for an additional floppy disk drive.<\/p>\n\n\n\n

The package I received contained the interface and a USB stick (which was already prepared for use). Unfortunately (as always), no instructions were included. \ud83d\ude42<\/p>\n\n\n\n\n\n\n\n

The buttons and switches have the following meaning:
\u2013 left side: Reset
\u2013 upper left side: up in the display
\u2013 second from the left: down in the display
\u2013 third from the left: make a selection
\u2013 first switch: Parados on\/off
\u2013 second switch: drive switching A\/B<\/p>\n\n\n

Anyone who has ever worked with an HXC <\/em> drive should have no problems using it. If you did not order a USB stick from Zaxon <\/em>, you will need to prepare one yourself. However, this process is exactly the same as it is for an HXC <\/em> or Gotek drive <\/em>.<\/p>\n\n\n

F\u00fcr mich eine der interessantesten Funktionen:
Ich habe einen gro\u00dfen Stapel an 3“-Disketten, die ich gerne archivieren w\u00fcrde. Mit dem DDI3 ist das jetzt ganz einfach. Man schlie\u00dft ein FD-1-Laufwerk<\/em> an das DDI3<\/em> an, erstellt auf dem USB-Stick einige leere Disk-Images und kopiert die Disketten mithilfe von Parados<\/em>!<\/p>\n\n\n\n

What happened to me during that?<\/strong><\/p>\n\n\n\n

    \n
  1. Initially, I simply connected the FD-1 drive. While this allowed me to access the floppy disk in Drive B, the DDI3 continued to display \"No USB Stick.\" It is, therefore, indeed necessary to modify the floppy cable used to connect the FD-1 to the DDI3. As described on Zaxon's website<\/a>, line number 10 must be cut. Afterward, accessing both drives works without any issues.<\/li>\n<\/ol>\n\n\n

    2. For copying, Parados<\/em>, which is integrated into DDI3<\/em>, can be used.
    Unfortunately, Parados<\/em> could not be activated for me with the command |drive<\/code>. \ud83d\ude42 The reason for this lies in the Vortex memory expansion installed in my CPC\u2014specifically, a portion of the expansion must first be disabled using the |DISBOS<\/code> command.<\/p>\n\n\n

    3. Parados<\/strong>
    Before use, it is worth taking a quick look at the     manual<\/a>. In my case, the settings for Drive B were incorrect (80 tracks\/DD).
    These can be adjusted to 40 tracks\/SS by pressing SHIFT+C<\/code>, followed by D<\/code>. Pressing SHIFT+L<\/code> \"logs\" a floppy disk\u2014that is, its contents are displayed. Subsequently, the files you wish to copy can be marked using T<\/code> (Tag). To mark all files at once, use CTRL+T<\/code>. Once everything is selected, the marked files can be copied using CTRL+C<\/code>.<\/p>\n\n\n\n

    4. Firmware Update (2024)<\/strong>
    Hard to believe, but after a long hiatus, I used the interface again and decided to check if there was any new firmware available. Since the DDI3 is essentially an HxC drive, surely there ought to be something to be found. Indeed, on the     HxC homepage<\/a>, there is a download link as well as instructions for the update.
    In the final section of the page:
    USB Stick STM32 HxC Floppy Emulator (HxC Firmware for Gotek)<\/em><\/p>\n\n\n\n

    I used the file from the following subfolder within the download:
    \/Firmware_Updates\/Generic_Gotek\/Standard_Firmware\/*.upd<\/code><\/p>\n\n\n\n

    I simply copied this file to the USB stick I use with my DDI3. Then, I plugged in the stick and held down both navigation buttons while turning on the CPC. After about two seconds, I released the buttons, and the update started automatically.<\/p>\n\n\n\n

    A new Version 4.2<\/a> is also available for the HxC Manager.
    If hardware such as the X-ME, M4, ULIfAC, or another board capable of utilizing ROMs is being used, the Manager can also be launched as a ROM.<\/p>\n\n\n\n

    Conclusion<\/strong>
    A truly excellent expansion for the CPC464<\/em> that covers everything needed to get started.<\/p>\n\n\n\n
