[ FLOPPY EMULATORS // IDENTIFIED HARDWARE ]
A2Heaven SDFloppy II
A model-specific record for a physical floppy-drive emulator. It distinguishes the emulator hardware, removable media and host-facing drive signals; firmware support alone does not establish compatibility with a particular machine.
MODEL IDENTIFICATION: PRODUCT RECORD: A2Heaven SDFloppy II. Compatibility is conditional on the actual host’s connector, controller, signal conventions, drive geometry, firmware and media configuration; do not infer fit from connector count or nominal drive size alone.
Recorded specifications
| Cataloged part | A2Heaven SDFloppy II |
|---|---|
| Manufacturer / project | A2Heaven |
| Product family | Compact SD-based Apple II Disk II emulator |
| Drive bay / physical fit | Small 48 × 40 × 20 mm board/enclosure; external to the computer or mounted separately. Not a standard 5.25-inch drive-bay replacement. |
| Host interface / power | Connects to an Apple II Disk II interface card using the device cable; SD card socket, image-selection/refresh buttons and activity/current-image/write indicators. |
| Removable media / image format | SD/SDSC/SDHC/SDXC with FAT16 or FAT32; reads and writes DOS 3.3 or ProDOS disk-image files in .DSK format, with up to 36 image entries per card per manufacturer. |
| Host compatibility | Apple II series computer with a Disk II interface card and compatible host configuration. It emulates the Disk II drive role; it is not a direct disk-port device like wDrive. |
| Variants and identification | A2Heaven SDFloppy II is a dedicated small Disk II emulator with its own selectable-image panel. Identify the board revision and SD card when documenting observed behavior. |
Compatibility and handling
- A Disk II interface card is required; check slot/card configuration and cable orientation for the particular Apple II model.
- Although the vendor lists broad SD card classes, use a known-good FAT16/FAT32 card and preserve a clean copy of source images.
- The manufacturer documents DOS 3.3/ProDOS .DSK images and read/write operation; do not assume WOZ-level copy-protection representation.
Before installation, compare the emulator’s exact revision and interface against the host service documentation. Confirm connector keying and pin one, power voltage/polarity, drive select, motor/disk-change signals, expected density and image geometry. Preserve a read-only copy of original disk images and configuration files before experimenting.
