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.

Together with the EuroPC and EuroXT stuff I also found BIOS versions for Schneider's Euro AT and Tower AT series.

The EGA BIOS provided came with the Tower AT v1.01 BIOS, the archive (also on the FTP) contains service manuals for both machines.

https://mega.nz/#!HIhAUBzS!R7hauLU-yzIClh6Eb7pax86PaX3KLgMNpKRn6k8NTv8

Unfortunately those AT BIOSs don't just slip into our existing at.cpp driver, some emitting short beeps, none displaying anything.

The Schneider machines were quite popular in Germany for a while. Most of them are 10 or 12.5 MHz 286 class machines with internal EGA graphics that could go up to 800x600x16, Windows 3.1 drivers are provided. Harddisks were 20-60MB. Later machines had 386sx CPUs and EGA. A "slice" with a tape streamer or a 1.2MB floppy was available for the tower machine as a case extension.
The name designations are somewhat erratic and not used consistently (Tower 220, 202, 240, 260) ... at first 3.5" 720KB disk drives were used, later they switched over to 1.44MB ones.

Check out the pictures on those websites, I don't own one yet.

After a long, hard (and expensive...) quest the last 2 Casio PV-2000 carts have finally been purchased and dumped, so the system is now fully preserved (released games at least). One hell of a milestone and now I will sleep better at night smile

Nothing to do with new dumps per se, but this guy just posted a nifty ROM utility.

Someone over on AtariAge dug up an old ERIC retail kiosk laserdisc. The kiosk consisted of an Atari 800 controlling a laserdisc player. I don’t know if we have the software but what’s the state of the art for archiving laserdiscs?

Laserdisc archiving is a charged political issue, in short nobody has decided on the best way to do it.
