The posted HDD dump seems to be a raw MFM image. Can I get actual bytes somehow?

mfm_utility can convert it
it's part of the mfm emulator toolset

i'll fire up my board and convert it

./mfm_util -a -m s6300_emu -e s6300_emu.raw
Original decode arguments: --sectors 17,0 --heads 4 --cylinders 640 --header_crc 0xffff,0x1021,16,0 --data_crc 0xffff,0x1021,16,0 --format WD_1006 --sector_length 512 --retries 50 --drive 1
Matches count 34 for controller WD_1006
Header CRC: Polynomial 0x1021 length 16 initial value 0xffff
Sector length 512
Data CRC: Polynomial 0x1021 length 16 initial value 0xffff
Number of heads 4 number of sectors 17 first sector 0
Interleave (not checked): 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

Command line to read disk:
--sectors 17,0 --heads 4 --cylinders 640 --header_crc 0xffff,0x1021,16,0 --data_crc 0xffff,0x1021,16,0 --format WD_1006 --sector_length 512 --retries 50,4 --drive 1
Found cyl 0 to 639, head 0 to 3, sector 0 to 16
Expected 43520 sectors got 43520 good sectors, 0 bad header, 0 bad data
0 sectors marked bad or spare
0 sectors corrected with ECC. Max bits in burst corrected 0

The German BASF company sold computers in the late 1970s and early 1980s ... their lineup seems to have been badge engineered from the US Digi-Log company.

I got a BASF 7120, a huge boat anchor with built in monitor and triple floppy drives that appears to be the German version of the Digi-Log Microterm II.

I'll dump its ROMs when and indeed if I manage to tear it apart - the whole grey plastic top lifts off, but all electronic goodies are underneath the monitor and drive assembly.
Unfortunately I have no software to go with the machine - I wonder if Al has something in the pipeline apart from the ad in the above link.
