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.

    Which riser cards work with the Intel SCB2 socket 370 motherboard?

    I've never used riser cards before. Which models are known to work with this motherboard? If I can get a riser card with 3 regular sized PCI 33MHz slots and then use PCI extension cables for each PCI card I use, I'm happy. It would be a dream to enjoy having a motherboard like this working in a standard e-atx tower case once I can figure out how to mount extra PCI cards in my case. I have a Coolermaster HAF 932 to use.

    Thanks for any help.

    I'm not seeing any combination risers being available for this board. Either you had standard vertical mounting cards or a 90 degree adapter for one card at a time for 1 and 2U server enclosures.

      The only thing I found which might work is this:

      https://www.ebay.com/itm/351253875268

      It only gives you PCI-X slots though, which limits PCI card compatibility. If your PCI cards have double keying on the front and back of the edge connector, it should work in a PCI-X slot. Older 5v only PCI cards won't fit due to keying.

      This riser board assumes the motherboard was designed for riser boards to begin with, and not a 90 degree adapter for a single card. While PCI is a parallel drop bus, a single slot can't be broken out into multiple slots in many cases due to the interrupt lines not all being connected. Electrical load has to be taken into account as well, most PCI cards get all of their power from the slot, and several power heavy cards on a riser can potentially damage the slot on the board or the board itself.

        As far as I know, that board was only designed for 1U/2U cases.

        https://www.ebay.com/itm/252900915744 is pretty much your only option.

        you MIGHT be able to find a generic pci-x riser with a BRIDGE chip, but a cursory ebay/google search doesn't find any I can instantly recommend.

        If you want a dual tualatin board with proper ATX spec, look for an Intel SDS2, Tyan S2688, or Asus TRL-DLS. Be prepared to drop a large chunk of cash for one.

        It is a mistake to think you can solve any major problems just with potatoes.

          The Super Micro P3TDDE is another good dual tualatin board, but they are very expensive.

          I see them on Ebay for more than MSRP when new. I paid around $400 for mine back in 2002 NIB.

            I'm not bragging, but I dropped $300 for my S2688, and a bit more for my TRL-DLS. But in all fairness, I've been looking for a TRL-DLS for over a decade, and it is NIB.
