What’s in Model B?

The Model B includes several improvements over the original Model A:

  • Built-in Apple II Compatibility – Model B is directly compatible with the entire Apple II line, emulating 5 1/4 inch disks, 3 1/2 inch disks, or Smartport hard disks all without the need for a separate adapter. Of course classic Macintosh and Lisa disk emulation is still supported too. The equivalent functionality of the original Universal Adapter is built-in to the Model B.
  • microSD Card Support – The SD card slot is now a push-push microSD type, identical to what’s used in most mobile phones. This will make it easier to find suitable SD card media, since the older full-size SD cards are becoming rare.
  • SD Card Hot-Swap – The SD card can be removed and re-inserted while the Floppy Emu is powered on.
  • Improved Protection Circuitry – Model B features improved protection circuitry on the disk drive interface connector. This circuitry will help protect the Floppy Emu from electrical damage caused by voltage spikes and surges. It also eliminates the risk of potential damage if an Emu board running the Apple II firmware is inadvertently connected to a Mac or Lisa computer.
  • Same Great Emulation Features – All of the time-tested Macintosh, Apple II, and Lisa disk emulation features from the original Floppy Emu are still present. Model B reads and writes emulated 140K, 400K, 800K, or 1.4MB floppy disk images, or hard disk images up to 2GB, if supported by your Apple computer.

Your Floppy Emu comes fully assembled and tested, and ready to use. It includes a 3 foot 20-pin ribbon cable for connecting to your computer, and a DB-19 adapter that mates with the 19-pin external disk port found on most vintage Apple machines. If necessary, this adapter can be removed and the cable can be connected to an internal disk header on the computer’s logic board or disk controller.
