Forum Rules and Etiquette

Our mission ...

This forum is part of our mission to promote the preservation of vintage computers through education and outreach. (In real life we also run events and have a museum.) We encourage you to join us, participate, share your knowledge, and enjoy.

This forum has been around in this format for over 15 years. These rules and guidelines help us maintain a healthy and active community, and we moderate the forum to keep things on track. Please familiarize yourself with these rules and guidelines.


Rule 1: Remain civil and respectful

There are several hundred people who actively participate here. People come from all different backgrounds and will have different ways of seeing things. You will not agree with everything you read here. Back-and-forth discussions are fine but do not cross the line into rude or disrespectful behavior.

Conduct yourself as you would at any other place where people come together in person to discuss their hobby. If you wouldn't say something to somebody in person, then you probably should not be writing it here.

This should be obvious but, just in case: profanity, threats, slurs against any group (sexual, racial, gender, etc.) will not be tolerated.


Rule 2: Stay close to the original topic being discussed
  • If you are starting a new thread choose a reasonable sub-forum to start your thread. (If you choose incorrectly don't worry, we can fix that.)
  • If you are responding to a thread, stay on topic - the original poster was trying to achieve something. You can always start a new thread instead of potentially "hijacking" an existing thread.



Rule 3: Contribute something meaningful

To put things in engineering terms, we value a high signal to noise ratio. Coming here should not be a waste of time.
  • This is not a chat room. If you are taking less than 30 seconds to make a post then you are probably doing something wrong. A post should be on topic, clear, and contribute something meaningful to the discussion. If people read your posts and feel that their time as been wasted, they will stop reading your posts. Worse yet, they will stop visiting and we'll lose their experience and contributions.
  • Do not bump threads.
  • Do not "necro-post" unless you are following up to a specific person on a specific thread. And even then, that person may have moved on. Just start a new thread for your related topic.
  • Use the Private Message system for posts that are targeted at a specific person.


Rule 4: "PM Sent!" messages (or, how to use the Private Message system)

This forum has a private message feature that we want people to use for messages that are not of general interest to other members.

In short, if you are going to reply to a thread and that reply is targeted to a specific individual and not of interest to anybody else (either now or in the future) then send a private message instead.

Here are some obvious examples of when you should not reply to a thread and use the PM system instead:
  • "PM Sent!": Do not tell the rest of us that you sent a PM ... the forum software will tell the other person that they have a PM waiting.
  • "How much is shipping to ....": This is a very specific and directed question that is not of interest to anybody else.


Why do we have this policy? Sending a "PM Sent!" type message basically wastes everybody else's time by making them having to scroll past a post in a thread that looks to be updated, when the update is not meaningful. And the person you are sending the PM to will be notified by the forum software that they have a message waiting for them. Look up at the top near the right edge where it says 'Notifications' ... if you have a PM waiting, it will tell you there.

Rule 5: Copyright and other legal issues

We are here to discuss vintage computing, so discussing software, books, and other intellectual property that is on-topic is fine. We don't want people using these forums to discuss or enable copyright violations or other things that are against the law; whether you agree with the law or not is irrelevant. Do not use our resources for something that is legally or morally questionable.

Our discussions here generally fall under "fair use." Telling people how to pirate a software title is an example of something that is not allowable here.


Reporting problematic posts

If you see spam, a wildly off-topic post, or something abusive or illegal please report the thread by clicking on the "Report Post" icon. (It looks like an exclamation point in a triangle and it is available under every post.) This send a notification to all of the moderators, so somebody will see it and deal with it.

If you are unsure you may consider sending a private message to a moderator instead.


New user moderation

New users are directly moderated so that we can weed spammers out early. This means that for your first 10 posts you will have some delay before they are seen. We understand this can be disruptive to the flow of conversation and we try to keep up with our new user moderation duties to avoid undue inconvenience. Please do not make duplicate posts, extra posts to bump your post count, or ask the moderators to expedite this process; 10 moderated posts will go by quickly.

New users also have a smaller personal message inbox limit and are rate limited when sending PMs to other users.


Other suggestions
  • Use Google, books, or other definitive sources. There is a lot of information out there.
  • Don't make people guess at what you are trying to say; we are not mind readers. Be clear and concise.
  • Spelling and grammar are not rated, but they do make a post easier to read.

    Write Disk Images to USB Floppy Drive

    Is there any software that will allow disk images (.img / etc..) to be written to USB Attached Floppy Drives?

    Trying to get some Disk Images I have onto Floppy Disks and the only way I have to get the .img to the floppy is by USB Attached Floppy...

        Be aware that you're pretty much limited to PC and modern Mac formats (i.e. 512 byte MFM sectors) under USB floppy.

        For the old CP/M machines you need legacy interface drives.

          WinImage it is.....will give it a shot....appreciate it!

          EDIT - Is there a trick to this? I have attached 3 different USB FLoppy Drives to my Windows 7 laptop and attempted to write a disk image to them from WinIMage

          Open the image, choose write to disk...it errors out on track 1 and from there my floppy is unusable unless I reboot...same thing happens again...these are 3 USB Floppy Drives that all worked fine before I tried them with WinImage...

            What kind of disk images are you trying to write?

            Note USB floppy drives only support 1.44mb and 720k disk images. And many don't actually support 720k like they should. Those drives need to be smashed with a hammer and left to rot on a pile of pulverized PCI winmodems.

            Most notably, DMF (1.7MB) disk images won't work.

              Just a simple .img file of DOS 6.22 to a 1.44MB Floppy....

              Once I have tried them in WinImage the disks dont work anymore at all, I cant format them or anything....not sure why...dont want to try to many more disks...

                Where did you get that .IMG file?

                Have you ever successfully restored that particular file to a disk before?

                Try formatting the disk(s) in a DOS computer before (and after unsuccessfully) using WinImage on them.

                Alternatively you could try using a DOS program to restore the .IMG.

                  IMG file from here - https://www.kirsle.net/msdos

                  I have formatted them in Windows with no issues before they try to write the image...but afterward they are unable to format or read or anything.. As for a straight DOS format, I have nothing at the present time hooked up with DOS running on it as my 286 crashed last night (great timing I know) when I was trying to see if I had the DOS images on it already to write to disk....

                  Do you know if DOSBOX would write an image to a USB Floppy? I know I could map to it via DOSBOX, but would it write? If so, I could give that a shot, but like I said, the two disks I have tried already using WinImage in Windows 7 just wont read any longer...no idea why.

                    Set your laptop to boot from the USB drive, boot to DOS, and then format those floppies from there.

                      None of the lobotomized "modern" BIOSes I have seen support low-level formatting USB floppies. They just ignore the low-level format int13 command, so it may look like it worked if the disk was already formatted. Tools like ImageDisk won't work with USB drives since there is no real floppy disk controller chip.

                      Also, most emulators don't talk directly to floppy drives. And if there is something wrong with the system, then you might still run in to the same problem.

                      But a few random ideas:
                      Winimage supports writing without re-formatting, and writing with formatting. See if one or the other makes a difference.
                      Perhaps try a newer or older version of Winimage.
                      Perhaps try running Winimage as administrator.
                      Perhaps try disabling virus scanners - some will incorrectly detect the old MS-DOS AV programs as viruses.
                      Make sure the disks format error-free on another computer.
                      Check that the Windows command-line formatter will format the disks unconditionally.

                        Linux usually has enough support to handle formatting floppies on a USB drive (cf. udisks), but if you're not familiar with Linux, it's going to be an uphill battle.

                          The formatter inside Windows XP/Vista/7/and so on will also perform USB low-level formats, but usually READS from the disk first, so it can often get very confused and die if the disk is not either completely blank, or already properly formatted.

                            Source code for the Windows sfloppy.sys driver is available online:

                            https://github.com/Microsoft/Windows...y/src/floppy.c

                            I added some of the USB floppy support (for example the USBFlopFormatTracks routine) to that driver during the Windows 2000 time frame. That must have been at least 16 years ago now. Been years since I last looked at that code. I sure it's been mutated somewhat over the years.

                              On my Windows 7 (64-bit) box:

                              1. Attached a 1.44M USB diskette drive. Noted that it then appeared in Windows 7 as drive B: (already have an A.
                              2. Ran WinImage 9.00
                              3. WinImage: Opened the first image file, Dos622-1.img

                              WinImage showed the contents of the image file.

                              4. WinImage: On menu bar, chose [Disk] then chose [Use floppy B:]
                              5. Inserted an already used 1.44M diskette into drive B:
                              6. WinImage: On menu bar, chose [Disk] then chose [Write Disk]
                              7. WinImage: In response to the 'disk is not empty. Continue?' type question, answered affirmative.

                              WinImage wrote the image. During that time, a 'Writing verifying' window was displayed, and that included a progress bar.

                              I then used the diskette to boot one of my computers into DOS 6.22 [pressed F3 after the SETUP screen appeared].

                              ----------------------------------------------

                              I then retried the operation using a blank diskette. The only differences were:
                              * the 'disk is not empty. Continue?' type question was not presented, and
                              * a formatting' pass on the diskette was done before the 'Writing verifying' pass.

                              ----------------------------------------------

                              In case it is relevant, the motherboard (980DE3/U3S3 R2.0) supports 1.44M drives (my A: is an internal 1.44M drive)
