Thanks, I read the Ipcas document?
I am fluent in german so I¡¯ll keep looking for further documentation, but so far I am unable to find the difference between the Ipcas, Gotek, Nalbatov devices, they all seem to be the same, even the Floppy Manager software is identical (only not in Chinese). I¡¯m afraid the devil is in the details, so there¡¯s no point to keep buying emulators until hopefully one fits, I believe there¡¯s a customization in the emulator firmware to support these old Sony drives.or perhaps there¡¯s a hardware (connector) mismatch as the post in the Keysight forum suggests. The winner would be certainly pulling the logic analyzer and digging in the original floppy signals (while it still works a little) or to find out what exactly other 8751A owners are using. Certainly a newer Sony floppy or a $20 Gotek emulator don¡¯t work out of the box.
