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.

    Help with Restoring an Altair 680

    Hi,

    I tried posting on cctech, but haven't rcvd any replies yet. I was wondering if anyone might know where I can get the logo artwork preproduced for the front on my Altair 680. This was an original computer my late brother bought as a kit back in the 70's. I helped him build this and we sure had some fun programming this. I'm finally getting around to restoring this. I dug it out from the last trip visiting them. All my stuff was stored in their garage since we moved. The logo silkscreen has faded away alot there's nothing left that resembles a logo. I was hoping there is some way to restore this, either by replacing the front panel or getting this repainted(or silkscreened). In the meantime, I can get the hardware cleaned up and hopefully get this to run again.

    thanks,
    =Dan

    You may get some answers here but I think, in this case, the Altair Computer Club may be your best bet. It's a much smaller group, of course, but with a tighter focus!

    One member has posted some silkscreening tips from his 8800 restoration which might be helpfull.

    It's on Yahoo Groups as Altaircomputerclub.

    Let me know if you can't find it and I'll dig up more specifics.

    Best of luck!

        Hi,

        Thanks all for the help. I saw from an earlier post on Altair Computer Club about using PhotoEZ to silkscreen front panels. That looks so great to use and easy to handle. I'm going to get some of this to restore my other machines too. But now I have to find somebody who has scanned a good version of the front panel for an Altair 680. I hope someone who has an Altair 680 could offer this.

          I have an Altair 680b. It was upgraded with an adapter card to accept s100 cards and eventually I added the Mikbug software in the extra 1702 eproms for motorola compatability. It stilll works and has 12k dynamic (s100) ram in it. I used to load software with a "Bit Boffer" interface from a tape player. The SWTP 8k and 4k Basic was modded to run in the 680b. I also modded the swtp co-resident editor and assembler for the 680b. Not sure if I still have it on floppy somewhere.

            I'm curious about which adapter card you have there. Where could I get a copy of the Mikbug ? I also like to try the SWTP basic, are those files availalbe too ? I could work with the original hex files to burn some eproms, just have to find some chips now.

              The adapter card was, If memory serves me correctly, in a Kilobaud magazine many years ago (late 70's). I had to etch the board myself and used wire wrap for the connections. I haven't been able to locate the software lately but I'm sure I still have it. The patches to the CO-RESIDENT EDITOR ASSEMBLER were in a Dr. Dobbs about the same circa. Lately I just used a PC to connect to the serial port. The Editor assembler is on a diskette in Motorola S format, so can be downloaded via the PC.
              I would have to dump the roms to get the mikbug monitor. The orginal 1K was moved to E000 addres to handle the mikbug while the 12K was starting a 0000. I will skulk around to see if I can find the SWTP Basic programs. Send me an email at v e 3 h d j @ r a c.c a if you still want them. I put spaces in the email hopefuly for some protection.
