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.

    Interesting indeed. OK. So that means that the Southern Cross 1 is a copy of the TEC-1. Hmmm. I did not know Peter Crowcroft, but I know Kitsrus is still going here. I was given the bits of the SC 1 by a friend who could not be bothered to build it up when he bought it and then lost half of the components. If it is an illegal copy then there will be no chance. Maybe I need to look at the TEC-1 for what I want to do. Thanks

      My friend Oceanway2009,

      You can send me your e-mail address and I will pass that along to
      couple of fellows who have the actual board with all of its components,
      and I will ask them to contact you and help you with the SC-I board that
      you have.

        Hi ziloo,

        Your help is much appreciated.
        Email is Oceanway2009@hotmail.com

        I was quite excited to get the kit as it was, but as someone who has had a lot of my designs and work copied, I understand the feelings of the original designer. Anyhow, I would like to use what I have for the purpose of demonstration if I can and will mention that it is a copy of the TEC-1.

          Well Oceanway,

          I gave your e-mail address to couple of fellows that are
          working on this board and hopefully they will contact you...

          Hope that helps!

            Hi Oceanway,

            The SC1 is indeed a clone of the TEC-1, but unfortunately this is quite common in the "hobbyist" industry and has been for a very long time.

            Even today I see examples of companies cloning others people's products, sometimes selling them for a lower price and thus competing with the original creators.

            With the SC1, you should not worry about legalities though as the original kit was released in the 1970s, and the SC1 was around for a long time afterwards and is now a long discontinued product. Therefore no one is really interested in it anymore, from that perspective. I do not remember exactly, but I think Peter Crowcroft might have posted to the aus.electronics newsgroup in the past where he clearly stated that the SC1 was a clone of the TEC-1.

            Regarding the monitor program, I think the TEC-1 and SC1 versions may be different. I also think I have a copy of the monitor program if you are interested? Were you able to get a copy of the manual, I can send that to you as well if you haven't already received it from ziloo.

            Ross..

              Hi Ross,
              Thank you for your reply.
              I am interested in building this thing up if at all possible, so would appreciate a copy of the manual and the monitor program. I understand the disappointment and annoyance associated with rip off and design copy and this has happened to me several times. ziloo has been helpful explaining the issue and I appreciate his help, but I don’t yet have a manual copy. Finding this out has really flattened my enthusiasm for this whole project. Maybe a double lesson for the kids I want to show this thing to. Anyhow, my email is shown above, I will understand if no one is prepared to help with this.

              Paul.

                I guess what we don't yet understand is what are you trying to do! If you are an
                engineer by trade, you know that you should ask your questions directly without mixing
                things up. You talk about legality of what you want to do, and then you talk about
                another board which could have a modified design and then it goes back and forth.....
                If you need a copy of the manual, having read the previous posts on this thread,
                you should/could have asked for one directly!

                I received a copy of an e-mail that was sent to you from a fellow who received
                a copy of the manual and put together a complete SC-I board, telling you that
                he is ready to help you! If you haven't checked your e-mail or you haven't
                received his memo, I will forward his memo to you and then you can directly
                communicate with him. You can't get an offer better than that! I will also
                send a copy of the manual your way....

                Let me know if you have received my e-mail!

                  Hi ziloo,

                  Thanks for the manual. I did email you back as soon as I get it. I have also been contacted by the fellow you mentioned above.

                  I am sorry if I have not made my intentions clear. I simply want to build up a micro system that is similar to the ones I worked with during my uni time in the late 1970’s. I do a lot of work with final year engineering students at a university here and run a defacto PIC course for students wanting to add microcontrollers to projects. There has been a lot of discussion about what it was like when I was at uni and what we had to work on, especially without all of the development tools available today. I asked around and got hold of a SC 1 kit with a lot missing. It was exactly what I wanted. My idea was to put it together to show the students and have some fun with it.

                  My issue with rip off copies is that I run a marine consulting firm in Hong Kong and have developed a lot of underwater sensing equipment, most of which has been completely ripped off by others at a loss to me. Unfortunately my company is not big enough to do much about it. I have now turned to PIC’s to be able to (at least) protect further development firmware. So to find out I am actually working with a copy, after actually getting exactly what I wanted, is a bit of a disappointment.

                  I hope my intentions are clear now. I will post some photos after I get it going. If you would like to know more about what I do then please feel free to ask or to email me.

                  Again, thanks for your help with the manual. It has made the assembly a hell of a lot easier.

                  Paul.

                    Hi ziloo;

                    I'm in the same predicament with regard to SC1. Could you be so gracious as to send me a pdf of the "Southern Cross 1" user manual. Thanks in advance.

                    Wayne

                        Hi,

                        I have just found a Southern Cross 1 Vintage Z80 computer but without user guide. Does someone have one and send me?
                        Thanks a lot.

                          Hi! Nice SBC, I am also interested in a manual !
                          Someone here actually built one? Seems like a refined copy of TEC-1B!
