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.

    Whats this??

    Hello i was watching this tv show from 1992

    https://youtu.be/cr2s1Eiu0s0

    but it has some lady using computers but what type are they and what software is being used? Thanks

    The best shot I could find of her actually using the system was at 8:20, and it looks to me like an ordinary 5170 AT with what is probably a PGC, based on the appearance of the CRT and the image display characteristics. It's possible the AT (given its processing abilities relative to '92) was an administrative terminal rather than the main graphics system, but given the probable PGC, perhaps not. Early on there's a wide shot with a PS/2 8560 or 8580 visible. The show implies the software is probably a PRPQ.

      The monitor has grey knobs so it's not a 5153 because they have black knobs so that's a 5154 EGA monitor at a bare minimum. EGA did support up to 640x350 in some video modes so it's plausible that that might be EGA.

        I thought of that, but you'd only get 16 greys at best from EGA, and you wouldn't get that on a standard 5154. So I'm pretty sure (but not 100% positive) it's not a 5154.

          A 5175 Professional Graphics Display monitor looks the same as a 5154 doesn't it? In fact aren't they almost exactly the same monitor inside?

            They are indeed almost externally identical, but the 5175 is an analog monitor almost-but-not-quite compatible with VGA. (It runs at 640x480 at the same scan rates, but I think it uses composite sync. Apparently adapters did exist.) I kind of wonder if that's a 5175 plugged into some other kind of graphics card because the PGA wasn't really optimized for paint-type programs.

              It's theoretically possible, but would be odd given IBM's involvement. I did a desultory search to see if any public records pertaining to the project are online, as happens sometimes, but didn't come up with anything. So probably we're going to have to live for now in a world where we can only guess.

                I don't think IBM would object to using a product they didn't make if it was something that filled a niche they didn't have an alternative. What makes this a little tricky is that some of the equipment in that video is clearly newer than a 5175 (the PGC was discontinued when the PS/2 line came out), and in that era there were better-than-EGA third-party options out there that could drive the 5175.

                The real reason for thinking it might be something else is simply the fact that software support for the PGC was absolutely dreadful and the card was, by design, really bad at raster graphics, but, who knows. If it's running some completely custom thing that IBM wrote for it that might explain why she's stuck using the AT and PGC when there's newer equipment sitting there at hand.

                  I don't know any details about this project, but perhaps the AT was upgraded over the years. Matrox as well as others built PGC compatible cards. They were supersets of PGC. Perhaps there was a requirement to maintain comparability with PGC instead of VGA due to software or non technical reasons. If the project required a CAD/high-end video card, IBM with its MCA, would have far fewer options.

                  PS: What is it with that description of the guy? It gets a bit specific, lines up cigarette butts in rows? It sounds more like a novel. LOL

                    Don't forget that this system had been in use and delivering results for some time already, by the time this television segment was produced and aired.

                      Well i did more research on the CARES system and this is what I found https://richhelms.com/rich/cares/

                      This guy came up with the system cares with IBM and that episode was from 1992 tv series Top Cops really intersting stuff
