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.

    RQDX1/2/3 latest firmaware and supported drives

    Hello,

    I am trying to format st225 and st251 connected to RQDX3 through M9058 but I'm getting error:

    controller has reported a fatal error in the format program
    status: rct write error

    what I should check to get an idea about the cause of this error?

    thanks,

    Andrey

    p.s. also I have couple of rqdx1(2?) cards, what drives they would support provided latest firmware is installed?

    #2
    RQDX1 supports RD51 (Seagate ST412) and RD52 (usually Quantum Q540).
    RQDX2 supports RD51, RD52 and RD53 (modified Micropolis 1325 or 1335).

      Andrey,

      Are you letting the controller determine the drive type, or are you specifying the drive type? By now you must know that ST225 is RD31 and ST251 is RD32. Go ahead and specify explicitly. Also, are you sure that these drives are fine? Even these drives are starting to show signs of weakness. Do they spin up fine or are the heads stuck?

      What are the rom revisions on the RQDX3? Also confirm you are using ZRQCH0 (revision H0 of ZRQC). Lastly, check to make sure that M9058 has all the right jumpers in the right spots and that you have the cables landed in the right spots. M9058 is extremely versatile.

        I get the same error with an RQDX3 and several RD53 drives.

          Hi Andrey,

          I've been playing around with ST225 and ST251 drives recently on both RQDX2 and RQDX3 controller. I've had no trouble formatting them with ZRQCH0.

          I have a page with some info about hooking up floppy drives and MFM hard drives on RQDX controllers -> http://www.avitech.com.au/pdp-11-03/rqdx-wiring.html.

          Scroll down to the section headed "Formatting an MFM Hard Drive", about half way down the page. It shows the dialog you'd normally get in a disk-formatting operation. Might help. If you still have problems, I'd be checking cables and jumpers. Are you starting with a known good drive? One minor thing to check is the jumpers on the drive itself, and that it has a terminating resistor pack fitted.

          Good luck.

            for now, I have tried to use an rqdx controller (two of them and couple of M9058 boards) both give same result:

                st251 is checked on wd ibm at controller and works ok. yes i'm using ZRQCH0 and i'm setting explicitly rd32
                what configuration can I do to M9058? seems there is no any, J9 connector is not connected at all

                  Did you remember to set the drive select jumper on the drive itself to unit 3 (or 4 for the 2nd drive) for use with the RQDX3?

                    ok, I didn't know that drive itself should be set to UNIT#1 (default is UNIT#0). Now rqdx3 is successfully formatted st251 hdd.

                    Is there way to upgrade rqdx1/2 to support st225/251? Is there any other firmware than original? I have an st506 drive clone 5mb, named SM5300, is there chance to use it also?
