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.

    Orange Gas Plasma displays

    I'm personally very fond of these displays, and I was wondering what other machines used them than the old Toshiba laptops and Compaq portable III/386.

    Anyone know more than I do?

    Don't forget EL displays! The Colby PC had one--offhand, I'd call the Colby one of the rarest of the luggables.

      The DynaMac had one. It's basically a Macintosh Plus motherboard in a clamshell case - looks kinda like a Toshiba.

        Wow, a classic mac with a gas plasma screen ... that's what the portable and Powerbook 100 should have been!

        AFAIK EL is just a display backlight for monochrome LCD, correct me if i'm wrong.

          Yes, they're very cool displays! I'm looking for a replacement for my Compaq Portable III, though it looks like MikeS may have a spare for me -- got shattered in shipping somehow.

          The IBM P70 used one too.

          IIRC, there was some sort of terminal specific to a mainframe system that used gas plasma displays for its terminal screen. The terminals were taller than they were deep, as a result of not having a necked picture tube in the chassis. Anyone know the name?

            IBM 3290.

            It was an expensive multisession terminal. And, being IBM, only works on IBM mainframes.

              Yup! That's the one I was thinking of! Apparently some of the PLATO computer systems used their own design with a gas plasma display too.

                While that was and is true for some backlights, that's a different thing. ELDs were used on the Colby, the DG One Model 2 and at least one Grid model. They're addressed in X-Y fashion, just like an LCD, but they're the active part. Freakishly expensive and usually found in military gear because they're nearly unbreakable.

                Here's Planar's line card for their ELDs

                  I'd like to see one of these ELDs, they sound interesting. Couldn't find any images on google though.

                  I noticed the plasma display on the Compaq portable III/386 and the Toshiba T3100e are both Panasonic units; the same exact model I think. Considering this, I wonder why Panasonic never made a laptop/luggable with a PDP screen.

                    Just look for any photo of a Grid Compass (1101). That used ELD, even though it looks like plasma (it's not).

                      Looks distinctly yellow where plasma is deep orange. I wish it hadn't been so expensive or we might have seen a lot more laptops using it. The same could easily be said for gas plasma however...

                        And then there was Burroughs who held some of the patents under which others made their plasma displays; here's one of their Panaplex TD700 terminals:

                          That's a nice little terminal, the display looks great on it.

                            I've a couple of "ITS" touch-screen banking terminals that used gas plasma displays. still well cool! Wish I knew how to program them

                              Red, Yellow and LCD

                              Was just posting something about couple GRiD palm systems and saw this thread, lot of the early Grid fifteen hundred series system that had the boring LCD display, or the red gas plasma displays or the very unusual yellow plasma fully tempested displays. The red gas plasma produced tons of radio interference so if you used one around any communications equipment it was a problem but the yellow plasma display was completely radio quiet, not only the display is special but the entire system was inside a double shelled case with filtering on all the inputs and outputs. The yellow tempested display was also used on the old fully militarized Compass system with the regular compass just having the red plasma. I have one of the military compasses that still have its program intact and operates from the early eighties, not a bad trick for a bubble memory. There are some pictures on a web page I really need to update at:
