Attention, retro computing enthusiasts!

We regret to inform you that AmigaOS 3.9 is no longer available for free download. Due to the harsh conditions of operating in wartime, we are forced to maintain server functionality and allocate financial aid to the armed forces of Ukraine, specifically purchasing camouflage nets.

Therefore, we kindly ask for your understanding and encourage you to consider contributing [$10 PayPal] to acquire this wonderful retro operating system!

Your support is greatly appreciated as we strive to preserve the legacy of Amiga computing.

Thank you for your attention and generosity!

  1. Sorry, did I miss something? The apparent download links only redirects to the folder which contains the links…? Anyone…? c”.)

    1. No, you did not miss anything. I see the big blue button, but it does not lead anywhere.
      Sorry this download is not for free anymore. Only by Donation $1 – $5

  2. Ciao e grazie per questo lavoro… una domanda: se scarico e installo, poi posso usare i vecchi floppy dei videogiochi anni 90′? Intendo con un normale lettore floppy esterno? Perché mi hanno detto che i lettori floppy Amiga erano dedicati e quelli in uso normalmente non leggono i files… Grazie in anticipo!! Roberto

    1. Ciao Roberto! Non sarai in grado di leggere e scrivere direttamente i dischi, perché c’è una differenza nel controller e nella registrazione delle tracce. Ma ci sono alcune soluzioni hardware basate su Arduino. Ti mando un link per il download via e-mail. In ogni caso puoi utilizzare migliaia di programmi della collezione Amiga.
