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.

    1993 SGI Indy for trade

    Years ago my boss gave me his SGI Indy that he had used for his research. He knew that I collected old computers and thought I would like it, which I do. But I'm trying to keep my collection more focused and although I do like a lot of the 1990's systems (Amiga!), I have been limiting my self to just systems from the 70's and 80's. I have many holes in my collection and would like to keep filling them even though it's difficult at this time. Long gone, I think, are the days of $40 C64's and Vic 20's.

    So if someone would like to start collecting in the Unix world with a early SGI Indy, I would love to trade this system for another one from the 80's. I already have a few of the usual systems (C64, Vic 20, TI99/4a, ect). So let me know which system you would like to trade and I will let you know if I already have it.

    The system dates from 1993, the first year they came out. I haven't yet tried to turn it on, but I can if needed. Judging by the 4mm backup cartridge, the system was running up to 2001. The CPU has a later 1994 date, which I think means that it was replaced because the first CPUs under performed (R4400 maybe?). There is an internal disk but I'm not sure what size. Same with the memory, but the memory slots are fully populated. It also will come with an external SCSI hard drive, external SCSI CD drive, external SCSI 4mm DAT tape drive.

    It still has the original keyboard, a Microsoft PS2 mouse, but not the original video camera (if it came with one?). It will also come with the IRIX 6.5 and IRIX 6.5.9 upgrade CDs and a GTCO cable (my boss said that he connected a GPS to the system through it). I also have a 13w3 to VGA cable (SUN) to make it easier to connect it to a monitor. All of the SCSI and power cables are included as well.

    If you need more or better pics, let me know. I live in Spokane, WA, USA for shipping concerns. Thanks for looking,

    I would love to get my hands on one of those old silicone graphics computers. Sadly I doubt I have anything you would be interested in. Also shipping would be rough to and from Ohio. I do have some C64, Atari, and Tandy Color Computer 2 but outside of the C65 executive model none of it is hard to find.


      Hi jimbox114,

      I have a lot of holes in my collection, so I'm missing even the easy to find systems. I am looking for an Atari 800 to match my Atari 400, so that might be something? I also don't have any of the later Atari machines (Atari 800XL, Atari 520st, etc.) I think that shipping is going to be painful no matter where it's going. I was thinking that I would pay to send the Indy (which is really heavy) and the other party would pay to send their system to me.

      Is that really a C65 you have, or is it an SX64? If you do have a C65, I wouldn't trade it for a SGI Indy if I had one.



        Here is the pictures of the external peripherals...

        4mm DAT tape drive

        External Hard drive

        External CD drive

        I have more pictures of them if needed.



          I have an extra Amiga 500 systems that i would offer for consideration. From a choice of 3 actually, in various external condition, one has internal memory expansion to 4MB iirc. Would come with PS and mouse.


            Hi vldmrrr,

            Sorry, I just accepted a trade for the system. Not that I wouldn't want a A500, I lost all of the Amigas that I had.



              This system is no longer available for trade. Thanks for looking.



                Learned about this too late!!! Shoot!
