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.

    "Turbo XT"


    This originally came with an RLL controller. I was told to throw the hard drive out before buying it due to personal data issues. Swap the Turbo MGP with a real IBM CGA card, add on a parallel port, give it an SCSI drive, and uh, well.... tada? It looks very mismatched. The more progress furthers, the more I'll post pictures.

    What's weird about this machine is that while it had a dedicated high density drive controller, drive 1 was jumpered to "1.44M" while the drive was actually 720K! This meant that the drive always had constant stability issues due to reading at an unreliable data rate; there are less issues now when I corrected the jumpers. However, often from time to time, the first cylinder still gets corrupted. Not sure if it's my only white 720K diskette that's being unstable by any means, DOS, or the drive just, well..... hating it.

    If you're going to ask me about the AT&T 6300, that's still a work in progress I need to find the schematics for the color monitor to see what happened to my beloved monitor.

    And of course the forum's image uploader is being stupid, let's get to the chase:

    P.S: Does anyone know where these cases come from? I saw the same one a while back in a 286 computer with a special badge on it. Alas, I would have taken both, but I chose to take only the XT instead.

      You really need to vet your advisers better.

        Nothing special about them; just scrapped one and still have one with (I think) a K5 in it, my workhorse for several years.



          Aaand the computer gets a more proper Gorilla monitor. Hey, it's not color, but it's very sharp. And it has horizontal positioning! Something that the AppleColor monitor could never do. To be fair, the CGA card with an AppleColor monitor could never do color as well. No idea if it's just the quartz crystal being flaky. The AppleColor also had weird problems where a color could throw the whole screen off.

            Well, it's a requirement here before buying anything.... Better safe than sorry.

              Interesting DTK Floppy BIOS version v1.04
              Could you please make a BIOS image and controller photo for

                I also used to have a case like that. A fairly nice compact case for baby-AT form motherboards.

                This was another generic Taiwanese case that was sold through multiple budget parts vendors. I'm thinking mine may have been purchased through JDR Microdevices.


                  I also think dumping the BIOS would be a good idea.

                    I think I'm going to switch back to a VGA card for now. It's unfair to have to choose if my Apple II or my C64 gets a monitor, since I only have two composite monitors currently.
