Reading old dos files


















By the 21st century, the rights to the products were sold and it's no longer available. Check this Web page for further history and discussion , including my correspondence with Chuck Guzis, president of Sydex and author of these programs. I don't have in hand the history of that product.

But copies of Teledisk, and images collected in ". TDO" format, appear in many vintage computing archives. Dave's program, on a vintage MS-DOS computer with then-ordinary floppy controller and drives, transfers disk contents to and from an "image" file. Thus his program can recreate the original diskette. He also has software tools on his site to test PC's floppy controllers and drives to support single-density operation, which is not not supported on some vintage PC floppy controllers.

Linux "raw" diskette utilities My ignorance of Linux is vast but I'm not clueless. Linux has some raw "file system" tools at the command line level they call it "the shell" or "the console" called simply "dd". Linux will also run some "Catweasel" hardware and software, discussed elsewhere on this page.

A more knowledgable colleage of mine, discusses dd, cpmtools, and working with Dunfield's IMG Imagedisk images, on a web page on his Web site. Note that hardware-operating tools like Imagedisk, Catweasel, etc.

Omniflop and Omnidisk, software to read non-PC diskettes Omniflop is a freeware product to read foreign diskettes on Windows-based PC's. Check the Web link for details. The site refers to other programs which do. See my [link to be added] Web page of S Web pointer for specifics.

Stewart described some attributes of Microbee disk formats and his ubeedisk program to me as follows: "My main interest is to archive Microbee disks which use 10 x byte sectors. Often side one of the disk has the sector headers coded as side 0, also some other strange sector numbering can be used. The Microbee used non-standard GAP values, and fiddled the sync bytes in their native format programs, like some other Microcomputers at the time.

So I need software that can cope with this and ImageDisk is able to do that. It also offers other useful diagnostics. Also needed for the Windows version, but not supplied with it, is a fdrawcmd. Other diskette utility programs which use this driver are linked from that site as well. Stewart noted his program was written around LibDisk tools and uses the LibDsk library.

It can read other disk image formats too but not write [them]". These generally connect to modern personal computers through USB. Others connect to vintage computer's floppy drive controllers, to operate as floppy drives but store on modern media like SDcards or USB flash-drives.

There are too many of these efforts to track. Some don't stay around long, and they often are limited to one particular vintage-computer interest. They may not provide file-level recovery. It's not my job to represent them or review them; my site documents floppy drives and diskettes for purpose, these are another means to access those.

But I can describe how you can find these devices with a Web search, and what you might consider when you do. Many have a Web site or are part of an email-based discussion group.

Some are individuals who are presenting these as their projects; some are selling them as products. In some cases, they offer their device as a solid-state floppy drive replacement on specific commercial products: sewing machines or industrial controllers or music synths - at several hundred dollars.

In the 21st century, there's inexpensive logic analyzers made from microcontroller modules and sold for tens of dollars, or available as open-source hobby projects. A logic analyzer samples one or more digital-logic signals, as triggered by other logic events. They are a kind of digital oscilloscope. Various people have added simple logic controls to or with these devices to operate floppy drives or hard drives! They force the drive to read tracks; the logic analyzer samples the data stream into a file.

So, before you dive in, read through some of the reviews. These vintage drives have much higher quality parts than the cheap USB drives now on Amazon. Most are still supported as plug-and-play devices by Windows Perhaps you even have one sitting around.

You can connect it to a generic floppy-to-USB adapter. You can rig an external power supply for the floppy drive with the proper adapter. Another option is to mount the drive and adapter internally in a computer case, and then use a SATA power adapter there.

The trickiest part is making sure the LAN networking between your vintage and modern machines works properly. It comes down to making Windows file sharing from different eras play nice with one another. If you have 5. This is because 5. It allows you to use an internal 5. Once you get it set up, the FC is definitely worth it, though. You can then use these with emulators or access them with a disk image tool, like WinImage.

The advantage of KryoFlux is it can back up copy-protected disks, or disks in many other system formats Apple II, C64, and so on , and it does so with a high degree of accuracy. The KryoFlux does have a few drawbacks, though. The same as the 3. There are other options, though. One is uploading the files to an FTP server from the old machine, and then downloading them from that server to the newer computer.

The process of reading floppy disks on a Mac depends on which type of disk you want it to read. If you have 1. You can still find these for a reasonable price on eBay. There might be some technical work-arounds, including restoring HFS support, but these are complex, and options are still emerging. Send your query to answer pcworld. My instructions are for Word, but can be adapted to other Office applications.

All of them have an Open checkbox—although only a few are checked. If not use 'cd' to change to the folder you chose during setup. Running an application or game is accomplished in exactly the same way as for the installer.

Simply use 'DIR' to list the files then enter the name of the. Close the program if it's running, open your file explorer and navigate to :. You can now start the IPX server, which will allow other clients on the local network to connect to you.

To get started, enter the command:. Windows Firewall may show an alert at this stage. Click 'Allow Access' to make sure multiplayer will work.
