I am trying to operate the Slim SD HxC Emulator as replacement for the floppy-drive of an Ando optical spectrum analyzer. The Device has a Teac FD-05HG floppy drive. According to the compatibility list it should work. However, I do experience problems.
With a SD-card containing the preconfigured files (From the HxCFloppyEmulator_DosDiskBrowser folder), I encounter an error when I try to read/write/format an emulated disk. Changing disks is correctly indicated by a number of beeps. When trying to write/format it fails reporting "No disk inserted".
I already added a 1k pullup resistor to R8 and updated the firmware to the recent beta version.
Are the issues related to the emulator hardware, to the SD-card and contents or both? I do have a floppy formated by the device but no PC with internal floppy drive available (just usb-connected floppy drive).
I should also mention, that I have ordered the wrong hardware-variant on lotharek (34 PIN instead of ZIF). However, I added an adapter 34PIN-ZIF so I assume that this is not causing any problems.
Best regards and thanks for any advice

Re: ando aq6317b
Some zif signals are not present on the 34 Pin connector so this may be the cause of the issue.
Have you the zif adapter schematic ?
Re: ando aq6317b
Sorry the late response, the notification got stuck in my spam-folder.
I've taken a picture of the adapter and tested the PIN-layout (see attachements). In fact several Pins from the ZIF are not routed to the 34 PIN connector.
Is there a schematics, how the 34 Pin connector should be connected to the 26 PIN ZIF or is there a general incompatibility and I need another PCB?

See the page 16:

The pins 8,9 and 11 shouldn't be unconnected.
Try to set them at 0 or 5V.
