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.

    16-bit generic sound card in XT?

    Hi guys,

    I want to run 8088 domination on my IBM 5155. Can I use this generic looking sound card in it. Seems that it only needs 16 for the CD-ROM drive, and there aren't a lot of connections to the 16-bit port. Also, seems to have an OPL3 chip on it, so that should work, right? Also is there anything I need to configure for IRQs?

    Wanted: Any old clunky 286-P1 machine that has some kind of working battery or replaceable with off the shelf parts. Preferred: 10+lbs 386 machines.

    Well, it's anyone's guess whether or not it'll work in an 8-bit slot, or with an 8088.
    You'd have to set the IRQ to 5 or 9; 9 is the highest an XT-class machine can support. And you'll have to make sure that whichever it is doesn't conflict with the IRQs currently used by your machine. Look carefully at that silkscreen.
    I don't see an interface for a CD-ROM, but it does have a modem -- that's interesting. Possibly useful.
    Current favorites: IBM 5160 (EGA+Hercules+PGC, 8 floppy drives, XT-IDE), DCC D-116 (Nova 1200 clone), ASR 33 Teletype, PDP-8/I (lots of issues, restoration underway)
    Wishlist: IBM 5161 (expansion chassis), Diablo 31/RK02/RK05 or equivalent, Data General equipment, and the meaning of life.

      Ewwwwww. It's a sound card that's also faking a modem.
      Well I see an OPL chip but as for which chipset it is (and it's likely emulating a SoundBlaster) you will have to peel the sticker off the chip to the right of the OPL.

        Lol I have no interest the modem functionality, there's a jumper to flip it off. CD-ROM is a much smaller(proprietary?) port in the upper right of the card. I can take a look at the chip under the sticker, I was thinking I'd need that. Can I just set it to IRQ7, I thought it can't get past IRQ7, not 9? I'm not going to be using my parallel port anyway.

        EDIT: Its an ESS AudioDrive ES688F

          ESS688F physically is a 8-bit chip (with integrated 16-bit DAC/ADC and 16-bit sound samples support but w/o OPLx).
          It can emulate SB 2 or SB PRO depending on GPI0 pin (55)

            Don't use IRQ5 on an XT class system. It's normally used by the hard drive controller.
            Use 7.

            Most cards work fine as long as they don't have a driver (which usually expects an 80286 or better). So I go for cards like the SB Pro 2.0 which often have jumpers to set the address/IRQ etc
            That card you posted looks awful but does have jumpers to set the sound card settings, so might work as long as it doesn't need special drivers for SB compatibility.

            It wont hurt to try.

            Just my two cents.

              Also what should I set for the DMA channel?

                that cdrom connector is the audio input from the drive

                  This card only uses IRQ lines on the 16-bit extension, and since it is jumper configurable it doesn't need the ESS configuration utility. So it should work in XT, as long as you are not using interrupts above IRQ7 (IRQ9 aka IRQ2 is fine).
