No, service manuals or schematics are unobtainium, unfortunately. This device is really rare, and there is only very little information on it on the web. It was distributed by Zadok, a dutch company, and it went under the name of "Double Dutch SAM-1".

This is how it looks inside, maybe the chips around the floppy port give some hints?
Thanks. Anyway the DP8473 Floppy controller is a chip designed for the PC world...

I think yes, the large chip is a DP8473N, apparently a floppy disk controller - datasheet is here: http://pdf.datasheetcatalog.com/datashe ... 6021_1.pdf

Edit: Oops, I did not see your reply because of the page break... sorry.

Yes. Retry with the PC modes.

Btw try these raw images :

Since the Double Dutch sectors layout seems to be equivalent to the akai S950 format, this should work.
(You probably still need to force the interface mode ;) )

Thanks, these raw images do work when the interface mode is set to IBMPC_DD!

Also, formatting of these images works - thanks a lot!

What did you do to create these? I guess I can use these as a basis now for all my other disks - still, how do I copy my "real" floppies onto these working images in HxC floppy emulator software? That's something I still do not understand.

With the hxc software export the image to the "IMG file (RAW Sector file format)" file type and change the file extension to "aka".
(the final file size should be 80*2*10*1024=1638400 bytes.)

Jeff, thanks again for your excellent support during the Christmas days - it's much appreciated and I will gladly recommend the HxC to everybody interested. I have a working system again and I feel my SAM-1 is much more future proof than it has ever been before.

For the record, these are the settings that work for the Gotek/HxC combi with a Double Dutch SAM-1:
- jumper set to S0, nothing else
- NG-firmware-version
- IBMPC_DD interface mode
- HxC software export to "IMG file (RAW Sector file format)"
