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.

    IBM Portable PC 5155

    I'm looking for an EGA Card that will work inside this computer by connecting to its internal monitor cable.

    I"m told the EGA Wonder does this, if anyone has this card for sale, I'm intereted, if you know of other cards that may work i'd be interested in that as well..

    THANKS!

    GEEKS WITH A GRUDGE!

    So how can you tell if the card supports the 5155 ? Is it the small
    6 pin connector near the back of the card ? Does the genuine IBM EGA
    card work in the 5155 ?

      I'm assuming the 5155 monitor is composite. There is a wire going to a connector on the CGA CARD from the monitor basically CGA composite output.

      So I would need a EGA card that has composite output, perferably with this inside connector.

        It's the 4 pin one with one of the middle pins missing (key). The 6 pin one (with one missing pin) is for the lightpen.

          Ok, so my card does have that. I'll try installing this into my 5155 sometime and see how EGA graphics look on the portable.
          Here's a pic of the card showing the pins.

            I have, at least, 3 ATI VGA Wonder cards (out of an initial batch of 24) and they seem to sell for a pretty good sum for some strange reason.

              The ATI VGA Wonder is a great card , look at all the monitors
              and modes it supports. And it even works in an 8-bit slot. I
              still have the original one (and box) I bought back in 1988.
              Think I paid around $200 at the time I also bought
              a NEC 3D monitor at the same time to go with this card, paid
              about $600 for that !

              Here's a scan of the box showing the details:

                The EGA Wonder is the only card I know of that is able to display EGA rez on a CGA monitor, albeit interlaced. Since all monitors are not created equal, there must be some out there that are better than others. It's also the only one I know of that works in a 5155, displaying EGA on it's internal screen, but the flicker will induce hallucinations after a couple hours of gaming. I wonder if the high-persistence CRT out of a Compaq is compatible with the 5155? That might actually make it usable...

                  Compaq vs. 5155

                  I might have to check that out. My 5155 is currently in pieces, so I'm half-way there.
                  For some reason the thought of an Amber Compaq & a Green 5155 seems very attractive.
                  Maybe I can even scrounge up a CRT from a B/W TV somewhere that'll fit.

                    The VGA Wonder will do EGA on CGA monitor too.
                    When I got my VGA Wonder card back in 88, I read about the
                    EGA graphics on a CGA monitor and so I hooked it to my
                    PCjr (CGA) monitor and tried the EGA graphics mode, talk about
                    flicker

                          I wonder... if it does CGA on a VGA monitor (I mean, fully)
