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.

    Photos of my IMSAI PCS-80/30

    Hello all,

    I got my first PC out of storage over the holidays. It is an IMSAI
    PCS-80/30 that I bought in late 1977. Fired it up and everything works!
    Trying to figure out what to do with it. I'm, well lets just say 70
    something, and neither of my kids will ever want it. There is a computer
    museum here in Colorado, but from what I can determine it is not set up to
    display computer systems as yet. Don't really want to sell it on eBay.
    Here are some photos -- please ignore the temporary computer desk -- a piece
    of plywood resting on some chairs in my basement.

    It will boot and run Northstar Dos, CP/M, and the UCSD Pascal p-code system.
    For those who might be interested, here are the details.

        That's neat. I'm not an expert but I've never seen an IMSAI like that with the built-in monitor and no front panel. We have an auction site here if you wanted to post it there (there's no cost to post and no percent taken out of the sale or anything. It's just a free posting site for us to use and 100% of the transaction is yours). But that's only assuming you'd want to sell it and/or ship it.

        Beautiful system.

          Thanks John, I will consider that. It is important to me that someone who would appreciate the system end up with it.

          The IMSAI PCS was a series of components, I don't know how successful it was. Here is a link to PDF file showing my original promotional material.

                You might also consider checking with the Computer History Museum in Mountain View. They may not have one yet and, if not, they may want it. . .

                  Hi! I'm not one to recommend sending classic/vintage computers to the museum (lets use them instead) but I think in this case its a good idea.

                  Yours is a truly beautiful system and should be preserved as is IMO.

                  Please consider.

                  Thanks and have a nice day!

                    That is a wonderful system, and not a version of the IMSAI that I've seen before. Just the documentation is a valuable resource, especially since a lot of it has never been scanned for online preservation.

                      I looked at their "want" and "don't want" lists. While they don't say specifically it looks like a "don't want". They include IMSAI 8080 and S-100 CPM Systems on the "don't want" list. The DigiBarn museum has a PCS-80/30 -- it was the system on which WordStar was developed. A preliminary search of other computer museums around the country shows 3 or 4 which list the IMSAI systems on their "want" lists, but all but one of those are in the collect and store mode. I would prefer that the system not just gather dust in a warehouse.

                      It would appear that to be really desirable, an IMSAI would have to have a front panel with all those toggle switches. If the IMSAI 8080 was a first generation Altair clone, then my system would be a second generation IMSAI (1977). The monitor program in ROM took the place of the toggle switches, and did a lot more as well. I built my system up by adding disk drives and memory to be a pretty robust software development system, which was my interest.

                        That is an incredible system. Very beautiful and very complete. If I had the money and you were willing to sell I would drive up there and pick it up personally. Whatever you do, don't trash it!

                          I have scanned many of the manuals (28 to be exact). See my recent post in the "Online Manuals Forum"
