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.

    Seen: AT&T 6300

    If you want/need a spare unit and are willing to take a chance: http://www.ebay.com/itm/AT-T-Persona.../391085173453?

    About $50 shipped if you get the minimum bid and choose UPS.

    I know this isn't an AMAZING find or anything, but I hate seeing 6300s go into the trash, and I have a cash flow problem this month so I can't rescue it myself

    Note this this appears to be without monitor or keyboard.

      Correct; this is a project for someone who already has a 6300 or M24 keyboard and/or monitor.

        If it had the keyboard, at least, I'd be interested; the monitor I'm sure I could work around (there's ways of getting a VGA card to work, I'm sure) though I would miss seeing all the old 6300 modes.

          Actually, ChuckG found out you can make a 1:1 6300-to-VGA adapter with only wires. It pumps out VGA-compatible signals (who knew?), so you get to see 640x400 after all. I don't remember where Chuck's post was, but here's the info: ftp://ftp.oldskool.org/pub/misc/Hard...put_to_VGA.pdf

            Oh wow. That's something to keep in mind, should I run into a 6300 with a working keyboard.

              Well, it should be possible use a standard PS/2 or AT keyboard driving a small MCU to generate appropriate keycodes if the appropriate keyboard couldn't be located.

                Hmm. I wonder how much different the 6300 keyboard interface is from, say, the 5150/5160 interface.

                  Somewhat. Different codes and supplied by +12V (there's a 7805 regulator in the keyboard).

                    I thought it was possible to build an AT&T PC6300-to-normal-XT keyboard adapter? I know I've seen the schematics for one, posted many years ago on CompuServe.

                      Could be--the maintenance manual probably has some information on that.

                        In my experience even if you have an M24/6300 keyboard that isn't the end of the problem as they seem to suffer without fail from needing a new set of capacitive discs which are a pain to make anyway!

                          If the codes are similar to an PC XT keyboard, addition of a voltage regulator and the XTAT adapter board might just do the trick with perhaps a little tweaking and a PS/2 keyboard.

                            Those discs are easy to make. I turned out enough for a TRS-80 model 16 in about 30 minutes. The trick is to just twist the punch through the material, not drive it through.

                              Back in 2005, my wife & I were moving and I was faced with doing a little downsizing. Most of what I got rid of wasn't a big deal...but I had an AT&T 6300 that I parted with...wish I'd known there were folks interested in them. I didn't have the keyboard, etc, so it wasn't much good to me. The other thing I really regret was that plain old NEC CGA monitor...the one that said "Multisync" on the front. Yeah...I didn't know what I had.

                              Salvation Army store wouldn't take it...gave it all to Goodwill...shortly after that I heard from somewhere they Goodwill was no longer taking computer donations...they probably pitched all my donations in the dumpster and grumbled about it the whole time. I still get a sinking feeling every time I think about it...

                              Heavy sigh...
