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.

    Any guesses as to what the microExplorer cards are worth?

      They have been selling on ebay for around $750.
      Looking, or do you have some?

        I have one, but not looking to sell. Just curious. Was that hardware + software or hardware only or ?

          Just the board. I have some software at http://bitsavers.org/bits/TI/MicroExplorer if you need it. I'd be interested in a known complete set of the later versions if you have it.

            I have 2 fx’s. One has the microExplorer cards and it has an internal drive. There are also 2 external drives. I don’t know what’s on any of them, but there were no microExplorer floppies included. I won’t be able to fire up either marching until I get a black SCSI Terminator. All this happened by accident as the seller never mentioned the cards and I didn’t know until I got home and discovered what it was.

            I’m a retired mechanical engineer and I attended a couple of AI seminars in the late 80’s, but couldn’t get any traction where I was working. I knew about Symbolics, but didn’t remember that they did Nubus cards and nothing about Texas Instruments at all. I wonder how many sets each company did?

            Anyway, funny how Life sometimes has this circular quality…

              I doubt that I do. There were no Texas Instruments floppies and the seller said that the discs, 1 internal and 2 external, had been wiped.

              On another note:

              The batteries look pretty good, but I have no idea how old they are. How do you open the battery compartments? I tried to slide them and also tried to pull them up, but I did not want to apply too much pressure.

                They have tabs on the end. A spudger edge should be able to free them without breaking them off, and even if you do, the battery will stay in just fine.

                  In the listing it says 4.1, 5.0, 6.0 and 6.1. Are those software versions? Have you seen any programs that were written to run on the microExlorer? Are there any hobbyist AI groups? I did a bit of a search, but found nothing so far…

                    Yes. I don't know how complete the 6.1 rev is. I think these are all just the base system with some TI options in the case of the Explorer releases.

                    I don't know of any official groups for the Explorer/Microexplorer. There are a few people around with board sets. A Explorer emulator exists

                    Probably the most active old lisp revival group right now is for Xerox Interlisp-D http://interlisp.org

                    Their motivation is to get their old lispm apps running

                      So far I have not seen any Ti manuals or floppy disks.

                      Do any of these markings have any meaning for you?
