No, I don't have gotten something off list jet.
I've heard from a friend that another friend that died in the menatime, had
managed to copy HP9121 disks on a plain PC with something like Super Copy.
The drive was used on some HP Computer that controlled a PCB assembly
system from Siemens in his case and that is from where my Drive is
coming from.
Additionally I've read somewhere that it should be possible to write
such disks on Linux with some utils, but I haven't had the time jet to do
some experiments myself.
I have an FreeBSD Computer with 3,5 and 5,25 inch floppy drives in the
same room as the 1631D, maybe I could try this tomorrow.

What's the problem with your drive? Set the Drives Address to 2, this is
the default and check the peripherals menu again it the drive could be
found. I've fiddeled around for some time until I got it going...
