anybody know more about this?
Well... this is the famous HxC floppy emulator, for which the firmware has been updated to support the DPX1.
Which is quite easy, because the DPX1 floppy disks have a known disk format layout.
BTW: this HxC also supports the Emax.
But... concerning the Emulator II: the HxC could only support the original EII disk format, if the disk format specifications would be known. If not, the HxC firmware can not be adapted.
Unfortunately we don't know all details about this disk format. 2 times 80 tracks, 540KB in total. That's all we know. And it probably doesn't use the 'usual' sector sizes, which for the HxC would mean that the EII would not be able to write to the SD card.
Probably the few specs we have are not sufficient for the guy who is working on the HxC.
But I was going to contact him about it.... I didn't do it yet.
I have been considering to try finding out the EII disk layout by connecting a Commodore 5.25 drive to my Vista PC through a custom serial adapter, and then use the low level programming interface of the Commodore drive to find out the disk layout. But that's not my biggest priority
