    Here are the Exidy/Micropolis drives side-by-side. You can see it's a rebranded Micropolis drive that has been painted and Exidy stickers applied.

    I expect it is the same controller (or very similar) soft-sector controller to your Display Disk Unit.

    Great series of photos snuci! Thanks for putting those up.

    I have a huge backlog of various types of 5" and 8" hard-sectored floppies from many different companies that I'm going to try
    to start imaging and recovering data from, along with some very obscure soft-sectored disks from companies like Milwaukee Computers.
    I'm working with a Sorcerer owner in Canada to recover his 16 sector disks. It isn't clear to me that Kryoflux or the various CF card to Shugart adapters support hard sector media.
    Does that reduce the recovery options to reading on the original machine and drives then copying to a new blank disc or perhaps using PIP to send out the serial port?

    There is little support beyond the Supercard Pro having an option to stop synchronizing the capture with the (presumed) single pulse from the drive's index sensor.

    Along with that is the problem these cards don't actually decode what they are reading in real-time, so there are no retries. You can end up with complete garbage if the head gets clogged
    and not even know it.

    Copying the data out the serial port is generally what people have done it the past with hard-secored media like Northstar and Vector Graphics.
    There is a better chance of recovery too if their drives run a little slow or are misaligned.
    I don't know where the existing Micropolis Exidy disk dumps came from, or how the copies were made.

    Unfortunately, in my world I have a big collection of media, and rarely have the original machine. In some cases, I don't even have one that's close.

    Typically for me I've only just found this thread. I've literally just got my Sorcerer/S100/Micropolis setup running so if I can provide any more info just shout.

    *edit* just for giggles I loaded up the HxCEmulator to convert Larry's CP/M .IMD into an .IMG and .HFE for a Gotek floppy emulator and the Sorcerer actually starts to boot but locks up at around track 6.

    It's definitely a hard-sectored controller?

    While looking for a dump of the Micropolis controller ROM to help @whizzi get his system up http://www.vcfed.org/forum/showthrea...Sorcerer-error I stumbled across this program from @deramp to image Micropolis hard sector controller disks from a SOL-20 out the serial port to a PC. Could be a good starting point for you and others like @dutchacorn with hard sector media to transcribe . http://deramp.com/downloads/processo...mage_transfer/

    Nope, mine is soft sectored.

    Witchy,
    Is your Soft Sectored system an 8" or 5" Floppy.

    If you can make a .IMD file of it with Dave Dunfield's Imagedisk Ver 1.18, it maybe possible to access the files in the .RAW file
    with cpmtools with this definition:

    Code:
    # Exidy Sorcerer - SS/DD, ie: 8" - 256 x 16
    # 77 tracks, 1 sides, 16 sectors/track, 256 bytes/sector
    # Bytes on the media = 1*77*16*256 = 315392
    #
    # EXI2  Exidy Sorcerer - SSDD 48 tpi 8" - 256 x 16
    diskdef exi2
      seclen 256
      tracks 77
      sectrk 16
      blocksize 2048
      maxdir 64
      datarate HD
      fm YES 
      skew 5
    # offset 8192       # 0x2000 = 8192
      boottrk 2
      os 2.2
    end
    I've used it on some other Images I've located.
    Code:
    $cpmls -f exi2 -D CPMdisk1.raw

    If it's a 5.25" Floppy, I'd really like to get a copy of th .IMD file.

    Thanks.

    Were there any harddisk systems for the Exidy ? Preferably with some info on IO addresses and/or controller so I can add it to my ARM Exidy emu.
    I find that little over 300k per floppydisk can be tight assembling large sources, because of the generated PRN file.
