Get your Apple II BOOTI on with this USB Hard Drive Emulator Card from David Mutimer, with firmware by Marko Ramius.

The BOOTI card is a block device emulator that allows you to mount up to 8 devices in the following computers:

  • Apple II/II+/original IIe/enhanced IIe
  • Apple IIgs
  • Laser 128
  • Apple ///
  • Franklin Ace 1200

Disk images can be in .po/.dsk/.2mg/.iso/.hdv/.do, as long as the image is in ProDOS block order (not track/sector order). You can convert DOS floppy disk images to ProDOS order using the dsk2po Python utility.

The BOOTI card supports two modes:

  • Block Mode with support for up to eight devices (all machines). This mode is limited to 65535 blocks of 0x200 bytes each for a total of 32 MB storage.
  • SmartPort Mode (only for enhanced Apple IIe and IIGS). This mode offers up to eight devices in ProDOS and GS/OS. In GS/OS, the size of a device is limited to 8GB provided that you use either an HFS volume or an ISO image.



  • Due to high demand, there is a limit of one BOOTI card per customer.
  • Some USB sticks work better than others. SanDisk and Verbatim USB 2.0 sticks (4 Gb or less) seem to work best.
  • You should be able to use USB sticks without reformatting. Just copy your files onto the root (top level) of the drive.
  • If for some reason you need to reformat, be sure to completely erase/wipe the USB stick. Do not choose Quick Format. If your USB stick is larger than 4 Gb, create a 4 Gb partition. Then format in FAT or FAT16 mode, with MBR.
  • On the Apple II, II+, original IIe, Laser 128, and Apple /// only use Block Mode. Do not choose Smartport Mode.
  • For the Laser 128, be sure to enable the appropriate external slot.
  • The use of a USB extension cable is not recommended – it may work but is not supported.
  • If you have DSK (DOS order) disk images, you can convert them to PO (ProDOS order) disk images using the DSK2PO Python Script.



Reflash the EEPROM Firmware

If your BOOTI card is currently working and you want to upgrade the EEPROM firmare:

  1. Add the booti firmware disk image to your USB drive and plug into the BOOTI.
  2. Boot your Apple II and immediately press ‘C’ to enter the BOOTI configuration.
  3. Change the configuration to put the booti disk image into the first device.
  4. Restart your Apple II and boot the booti disk.
  6. Follow the prompts to flash the EEPROM, then restart your computer.
  7. Immediately press ‘C’ to enter the BOOTI configuration and look in the upper right to verify the firmware version.

If you are using a blank EEPROM or your BOOTI card is not working:

  1. Put your BOOTI card into one of the Apple II slots lower than your regular disk drive, so that the regular disk drive boots first.
  2. Create a floppy disk with the booti firmware disk image (or boot the disk image in some other way).
  3. Start your Apple II and boot the booti disk.
  5. Follow the prompts to choose the correct slot for the BOOTI, wait for the flash to finish, then restart your computer.
  6. Immediately press ‘C’ to enter the BOOTI configuration and look in the upper right to verify the firmware version.

    The booti device works wonderfully now on both my Apple IIGS and IIe. The key item to remember is that all files (disks) used by the booti must be in prodos order . I greatly appreciate the after sales support provided by Chris and David to address my issue and i love the device. Thank you both!

    Works flawlessly in my enhanced IIe. I have a card in slot 7, so for now this resides in slot 5. A short USB extension from adafruit lets me access it from outside the box. I would recommend a piece of plastic just as insurance against shorts with neighboring cards in higher slots tho.

    Fast & responsive performance from USB & intuitive menus – terrific product. Super quick to install, too. My configuration: slot 7 | Enhanced Apple //e.

  4. DDE (verified owner)

    Awesome product, and I can confirm it works with my Franklin ACE 1000. Easy to configure and just Total Replay by itself makes it worth it. I first played Karateka back in 1984 on a Franklin ACE, and I just played it again today!

  5. Evan Wright (verified owner)

    It’s awesome. I have one in my enhanced //e and it works great.

    Have one of David’s Multi-ROM adapters too. Love this thing!!

    First saw the Booti card on the Assembly lines Youtube channel. I really didn’t think to much of it at first but the price was great. Once I got the card and realized how easy it was to create 32MB prodos partitions and mount disk images I was sold. Mostly used it on the IIgs and its FANTASTIC! Backing up and restoring has never been so simple! I sold the card because I thought I could just buy another, but supply and demand! Thankfully I was on the wait list and I have another one on the way! I hope you guys keep selling this card for years to come because its one of the best boards for the Apple II out there!

    Works successfully with my PCPI compatible CP/M card. Well worth it!
    (FYI, the BOOTI card is incredibly tiny….)

  9. Georg Basse

    Fantastic card, works without problems in my enhanced Apple //e. Looking forward for another card to put in my Apple ///.

    I first heard about the BOOTI through a lot of chatter in a facebook group and decided to give it a try. I received mine a few days ago and installed it successfully in my Franklin Ace 1200 (1000) and it works flawlessly! Now I have so many options available to me, including many games of Swashbuckler!!! Thank you!

    • Chris Torrence

      Thanks Kevin, really appreciate your comments. And yes, Swashbuckler! One of my favorite games, although I can never seem to reach 80 kills…
