Forum 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.

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.

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.

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.

"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.

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.

    Not sure if the same commands will work, but here's a list from wikipedia:

    format [options] drive
    FORMAT drive: [/V[:label]] [/Q] [/F:size] [/B | /S] [/C]
    FORMAT drive: [/V[:label]] [/Q] [/T:tracks /N:sectors] [/B | /S] [/C]
    FORMAT drive: [/V[:label]] [/Q] [/1] [/4] [/B | /S] [/C]
    FORMAT drive: [/Q] [/1] [/4] [/8] [/B | /S] [/C]
    /V[:label] Specifies the volume label.
    /Q Performs a quick format.
    /F:size Specifies the size of the floppy disk to format (such
    as 160, 180, 320, 360, 720, 1.2, 1.44, 2.8.
    /B Allocates space on the formatted disk for system files.
    /S Copies system files to the formatted disk.
    /T:tracks Specifies the number of tracks per disk side.
    /N:sectors Specifies the number of sectors per track.
    /1 Formats a single side of a floppy disk.
    /4 Formats a 5.25-inch 360K floppy disk in a high-density drive.
    /8 Formats eight sectors per track.
    /C Tests clusters that are currently marked "bad."

    I saw that you are using IBM-dos so that's why I am not sure.

      Longshot, but if I were to make a DOS boot disk in Windows, would it read and boot a more recent DOS version?
      Not a double post, just posting as Tupin is posting.

      I have both 3.5 and 5.25 cleaning kits if you need them. Let me know if nothing else works. it could also be a bum floppy drive; gibberish data, not reading ot general error, might be indicitive of a bad drive.

        The cleaning was going to be my next step. I don't know where I would find a 720kb floppy drive, can I just use a 1.44 MB one? I have one from an old Macintosh.

          You could use a PC 1.44MB one, but you will find the Mac floppy is not going to work, at least not easily. Apple supplies the power through the ribbon cable and many of their old floppy drives are also electronically ejected - i.e. no manual eject buttons. This also has additional signals on the ribbon cable.

          Find a PC 1.44MB drive. It will work as 720KB in a DD controller.


            Doesn't it need an edge connector type connection rather than pin type?

              The original Tandy 1000 can use standard floppy drives and any standard floppy drive cable. (The newer 1000 series machines integrated the power voltages with the drive connectors, requiring the use of specially modified floppy drives, but you don't have to worry about that.)

              The only thing to watch out for is that instead of putting a twist in the cable between the A: and B: drive connectors, Tandy used the Drive Select jumpers on the floppy drives themselves to configure the A: and B: drive positions. So when installing new floppy drives, you can either set their DS jumpers to match the proper Tandy configuration, or you can just replace the floppy drive cable with a standard PC cable with the twist, and then you won't have to worry about messing around with the jumpers on the drives.


                How do I change the jumpers?

                Got the drive out. It's a Sony MP-F63W-72D. I'll clean the drive head, and try again.

                Wait a second...This PCB on the edge comes right off. This looks like some sort of adapter to use a more modern floppy drive on a Tandy...


                  the sony drive gets it's power from the date cable, not the molex cable, that little guy makes it so you can use the drive in a normal pc without modding a cable for the tandy, if the sony drive doesn't have a 4 pin mini plug on it, like the 3 of mine do.
                  Nothing beats the roar of a 36yr old drive coming to life after a decade in storagg


                    So I could I take a floppy drive and replace it using that board?


                      Looks liek it. I would think based on what AI am looking at, you would need a power cable from go from that larger plug to the one the drive uses.

                      If the Sony drive you have uses the data cable for power, that drive might not work. See if you can find a plain vanilla floppy drive, your local thrift shops might have one in a five-dollar old machine.

                      If that card is for a specific floppy drive, then it might not work at all. I'll look around, see if I can dig up an I/O card with a floppy drive header on it (if you need one). 8-bit ISA, right? Not the full length ISA card card? I'll start looking.

                        The Sony drive has a standard connector and four-pin power connector. That adapter gives it an edge connector and a bigger power connector.


                          Okay, now there are bigger problems. The 3.5 inch drive responds, but it still doesn't read anything. The 5.25 wasn't working, so I switched the cable on the 3.5 from J2 to J3, and they both booted up, but neither responded.

                          I'll use my Tandy 1000EX for now, I'm getting a DOS game in the mail soon.


                            Tupin, what i see on that adapter is the molex for the large plug, but NO power to the 3.5inch, i believe it lets you plug in the tandy drive and be able to use it in a standard pc, i would be careful when using that particular model of tandy floppy, the 4-pin mini and the lines for the power on the cable ARENT seperate on the drive, the traces connect into each other, if you use a standard cable, u will ground out the floppy and the power supply won't turn on, if you use the 4-pin with the standard cable, same thing will happen, the PS won't start, i believe that adapter rids u of that problem, or make a special cable by removing the ground pins one of the connectors, then marking that cable as specially modded.

                              Getting lost over here. Does the floppy drive need that controller? My Tandy doesn't use that card, and it uses the power supply and no plug on the card at all. I'll open it up tomorrow and take pictures, see if we can compare notes. If necessary I might have a suitable drive extra.

                                Still need help. Either both the floppy drives go on at the same time, only the 3.5 inch drive goes on, or neither go on. There's a cable with a black connector and a gray connector, the 5.25 inch drive has one edge connector, while the 3.5 inch has 2. Which ones go to where?
