5.25" floppy drive to IDE to USB?
For the PC floppies, you can make disk images on an modern PC with 1.2M setting in BIOS.
GNU dd is available for every OS out there. I used it last on Win2K: dd if=//./b: of=name.img Once you have the images, WinImage or equivalent will open them, no need for VMs. "Anthony K." -removeme wrote in message ... Arno, since you asked what I was trying to do: I have a collection of good condition single and double sided 5.25" floppies from a couple of different systems: PC DOS and Apple II. Some of it is old data I'm curious about, but most of it is vintage software and games. My goal was to make images of the disc for use on a modern computer, using virtualization software to emulate DOS and Apple II. This would be more convenient for me than maintaining two more computers. It's enough I've got to deal with C64 and Amiga stuff too. I can always go the PC + Slackware route, or just enjoy the disks on a vintage machine, but it would have been nice to have to explain why I need to buy yet another old computer. |

The worst case scenario, I end up with another shiny new vintage computer. I was told elsewhere that I might have luck if I track down a first gen USB 3.5" floppy because it might also contain the logic for a 5.25". There's some possibilities yet. Anthony |

Anthony Apple II disks are GCR, but fortunately 48tpi This is a few million miles away from any standard IBM compatible controller. I think Commodore also used GCR and sometimes 100 tpi drives. No USB device will handle these types of disk as clock and data from the disk need separating and processing in a very different way. You need to find someone with a multi-media disk reader, such as in InterMedia, US Lynx convertor or Shaffstel system In UK, try www.onetouchcomputers.co.uk Michael |

Unlike almost every other 3.5" USB floppy drive on the market, Buslink makes (brands?) a large metal-cased one which contains a standard 3.5" drive and a USB-to-floppy bridge board using standard connectors. (In almost every other such product, all of the electronics are integrated into one board on the drive mechanism itself, making it impossible to access the floppy data bus). It wouldn't take much work to open this thing and (using a card-edge connector adaptor) connect the bridge board to a 5.25" floppy and see what happens. |

Try searching for any of these: "Catweasel mk4 Plus", "FC5025 Floppy Controller", or "Kyroflux" These are disk drive controller cards for modern computers. FC5025 is a USB solution. CatWeasel is a PCI card. Kyroflux is still in development. |

Can't recall when 5DD went away (XP possibly) but suspect that you could do it on a 98 box and make the drive available on the network. |

Is it possible to get a vintage 5.25" PC floppy drive connected to a modern PC with no floppy controller and just USB/FireWire inputs? Do IDE 5.25" floppy drives exist? If so, I could drop one into a USB enclosure. Is there an adapter that would let me connect a floppy drive to an IDE interface? My specific machine is a Macintosh so I'm certain there are additional BIOS issues, but I figure, as long as I am able to get the drive mounted via USB, I could run Windows or just virtualize DOS in order to see the drive properly. Any ideas? Anthony K. What about an Ide to 5.25 and 3.5 chord will that work for you ?? |
