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.

    A tale of 3 CGA monitors - help wanted fixing them

    CGA monitors are not exactly easy to come by. And even harder to come by in still working condition.

    I have the following:

    Sysdynei CD 1343. I really want this one working and stable. This model has a main power button on the back, and a 2nd power button on the front. The back button is the main power, it needs to be on to use the front button, that turns the display on and off. When I received it, I could power it on with the back button, press the front button, and get the clicking sound of it turning on, and turning off. But no picture on the tube. I opened it to look for any obvious things, couldn't find anything, put it back together carefully, and now the front controls do nothing. Not sure if I missed a connection, or disturbed something so that a poor connection isn't connected now, or if it's just the same problem but gone further. But, the main power does still power it on and off - I get the familiar ticking sounds of it turning off from that back button, which I know is normal for this model as once upon a time I had a working one.

    Amdek 722. Turns on - extremely blurry picture. Possibly could be adjusted from the inside? Probably needs more than just a focus adjustment though, the picture really looks awful. Would be a shame for it to continue collecting dust if it could be fixed up and used by someone.

    Casper HD-55. My only working CGA monitor at this time. Vertical hold is a little finicky, could probably use a little work to stabilize it....but as is, it's very useable.

    At the end of the day, I'd love to have the sysdynei monitor working, I'd like to have a working spare, and I'd be willing to part with the Amdek or Casper as part of a deal to have the Sysdynei fixed up.

    I'm located in Massachusetts. I do travel to Jersey frequently as well.

    Start with the electrolytic caps in the first one. The symptom sounds familiar. The Amdek could be suffering a similar fate with lower-than-normal voltages.

      Thanks for the suggestions. While maybe I might try changing a capacitor here or there when it's obviously bad and easy to get to, fixing dead monitors is not something I am capable of, or looking to learn to do. This thread is to search for people that can do the repairs, or advise on finding people to repair monitors.
