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 XGA-2 Adapter for Bermuda motherboard

    Hi,

    IŽam looking for one or two Ibm Xga-2 adapters for my two Bermuda motherboards,

    I have got 2 Bermuda motherbords and a risercard from a friend, but iŽam not able to test them, whitout any graphics card.
    I have been looking at Ebay, but I have not been able to find any in Europe
    Perhaps someone knows where to find them ??
    The costs for a card shipped from the US will be insane (not to mention the import tax )

    I have a running model 57 486Slc2, and perhaps i could fit the Bermuda motherboard in that one - just to see if it works.


    Regards

    Carsten

    I think I have an original XGA card I don't need, if that would be close enough.

      Great, thanks.
      It will be close enough.

        Carstenl -- I got a private message from you but it came out as blank. So I sent you one, and hopefully you'll be able to read and reply to it.

            Probably not an issue, just bear in mind that the riser cards are specific to the particular planar. Not interchangeable with other PS/2 models.
            PS/2s--M-30,M-40SX,M-50Z with AOX Micromaster 386DX, M-57, M-70, M-77, M-80

              Hi,

              Yes i have noticed, that the risercards are different types
              I have been looking here. https://ardent-tool.com/76_77/Bermuda.html

              I was lucky to get a risercard for a model 77 for about 17$

              They do also have a motherboard for a model 8595 !

                Early Riser P/N 27F4625 / 27F4630

                This riser is bare of anything to the right of the MCA slots but the battery/speaker connector.
                Newer Riser FRU 64F3732, P/N 27F4625, 64F0774

                This riser has an addition of a resistor, a 74F08, and a bit of wiring on the back.
                Late Riser FRU 27F4666, P/N 64F0808, 64F0809

                  I have got the FRU 87F4836 for my bermuda board - I do not know if it is a new or old version ?

                  I have installed the Bermuda board and the riser card + the XGA-2 card from vwestlife in the model 57 case, and it is working just fine.
                  The only thing that is not in use is the JMP3 - Logiclock header. I was not sure if the machine would start without it, but it started up just fine.

                    I'm not aware of any "old" or "new" references for a Bermuda riser - the response with images shows the Model 55SX (and 55LS/53SLC) risers (along with photos I did for the 'Ardent-Tool'). XGA-2 is a good choice for Bermuda video, but certainly not the only one. Either of the 'SVGA' adapters (like Brandon Bishop showed in now-running 9595) works well too - and the 'Eagle-BVE' doesn't have an ADF.

                      There are a number of improvements to the XGA-2 (also referred to as the 'XGA-NI', for "Non-Interlaced') - but yeah, I have more spare XGA than XGA-2 myself.

                        Pity that the SLC2 planar got displaced, but maybe only temporarily? - I'll be doing some benchmarking between the CPUs on those planars soon.

                          The OP has both an XGA and XGA-2 coming his way.

                            The XGA-2 is working very well in the machine, and I will keep the XGA card for spare use - the MCA cards are very difficult to find in Europe
                            The machine is running Dos and Windows 3.11 Danish, and I will install a few small games on it too

                            I have temporarily exhanged the SLC2 planar with the Bermuda, because I have some problems with the SLC2 Riser card, after I changed the Cmos battery.
                            It was the only way to have a running system. I hope that I can get the SLC2 planar to work with the riser card again.

                            If i can not get the riser card to work, is there anyway to get a riser card for the SLC2 planar, ?. -
