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.

    Caution about AMD socket 754, 929, etc.

    I have an old Socket 754 system here that I occasionally power up to do some rare tasks. Recently, I kept getting thermal shutdown issues, which was a bit perplexing as I don't load the thing down. Yesterday, I popped the top on the case and had a look-see. Much to my surprise, the retention tabs on the heatsink mounting had completely broken off, leaving heatsink and fan flopping around. In fact, the whole plastic bracket is brittle and I can break bits off with my fingers.

    Fortunately, the retention bracket is available and inexpensive. But I thought this was worth a caution.



    The Scythe universal (steel) brackets are discontinued, but frozencpu.com apparently still has them in stock.

    I've not had issues with the hooks breaking off in any case other than going Conan on it when installing the heatsink. But I guess they are getting to be that age where plastic becomes brittle after years of heat abuse.

      Now that I'm the proud owner of 1 socket 462 mobo and 11 cpu's, anything I need to know?

      Anyone need a socket A/462 microprocessor? Just pay shipping. I'll compile a list on a need to know basis.

        The surprising thing to me is that these retention brackets weren't done with PA6 glass-filled nylon.

        I haven't had any problems with socket 462/ socket A boards; if you're ambitious, it's possible to modify one of those boards to take the Athlon XP-M (mobile) CPU. The benefit is that the multiplier isn't locked, as it is on the Athlon XP CPUs.

          I had one break as well a few years back. Most likely it was a cheap aftermarket bracket. The system will slow down or shut down when the CPU gets hot so nothing breaks (unlike early Athlons).

          If you want a hotrod Athlon XP you might as well get a motherboard with 400 FSB and the last gen XP 3200+ CPU with 400 FSB since they are inexpensive. I think the mobile XP's top off at 333 FSB.

            I'msure it is because you've been erasing too many EPROMs. A little bit of ozone each time and plastic fails!!

              Dwight--I haven't erased a UV EPROM in perhaps a decade. EEPROMs and flash for me.

                My board only has a 333mhz bus. The croatian chip is an xp 2600+, and worked, once I got my act together. I'm just happy I have a working board. In general I won't even consider a mobo unless it's SEALED nos. But people lie. My bag was opened. Sometimes people just have to gaze upon something brand new and open it. Sometimes they use it for whatever length of time then put it back in the bag. Then it becomes born-again NOS. Not an official ebay category that I know of. But there are loads of products that undergo a true religious experience. They may even have some residual baptismal moisture lingering about. Maybe that's what's meant by seller refurbished. The refurbisher just happens to be God though. And automatically it's kosher for pesach too.

                  I buy whatever looks interesting and is cheap so used. Sometimes you need to replace a capacitor but no big deal. You can find old server boards still NIB on ebay (somebody kept them as spares and were never needed I assume).

                    My amd board was .99$.

                    Yes sealed box server boards are the most. But right now I'm spying an open box/no box mondo server board. It's as unconventional as you can get. In every aspect.

                      update

                      I finally received my Scythe "Universal Retention Kit" today. Very nicely done; all metal. Went onto the the Socket 754 board easily and fits precisely. Instructions say that it fits Socket LGA775, 1156,1366 (Intel) and 754, 939, 940, AM2, AM2+, AM3, AM3+, FM1.

                      Frozencpu.com still has a few in stock. Other vendors seem to have discontinued them.

                      The interesting thing is that the original (plastic) backplate was also starting to disintegrate. And here I thought that all backplates were metal...

                        Frozencpu is still around? I haven't heard that name since I was doing UV mods to my antec case in 2004/2005.
                        It is a mistake to think you can solve any major problems just with potatoes.
