Forum 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.


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.


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.



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.


"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.

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.

    My Latest Buy (5160)

    Hey guys,

    Just got this off eBay tonight. I can't wait to get it! It'll be my first IBM PC! I believe this is the 5160, judging by the 8 ISA slots.

    Here are some pictures:

    Can anyone tell me anything about what I just bought? No monitor or keyboard, unfortunately...

    If you can get a 8-bit VGA Card you can use a standard VGA Monitor XT keyboards are not hard to find.

      Great computer. I can't believe how clean and shiny the insides are.

      XT-keyboards are easily found on eBay. Maybe one of our members is looking to get rid of one? You will have to determine what type of video card it has when you get it. Most likely it will require a 9-pin ttl monitor. Those come available often enough on eBay. Or, you may want to set it up so you can use a conventional 15-pin VGA monitor. Those adapters aren't too difficult to find. There was a recent thread discussing 16-bit VGA cards that will also work in an 8-bit ISA slot like the IBM 5160 uses. You just have to know which ones are compatible.

        It may be cheapest to just get the XT-AT keyboard converter if you have a spare PS/2-style keyboard kicking around. Of course, all of the keys on the newer keyboard are in the "wrong" place...

          But I want a clicky keyboard so bad!! Haha! I might see if I can find an XT-AT converter...I think my neighbor might just have one!

          I can use the CGA card with a composite monitor, like my Commodore 1702, right?

          Can I run DOS 6.22 on the XT?

                Your neighbour! If you're referring to something like the adapter in the center of the picture below, then it won't work. That adapter only allows for the different type of connectors. There is an electrical difference between keyboards for the PC and XT and keyboards for the AT and PS/2.

                So you either need to:
                1. locate a keyboard that is specifically for the PC or XT, or
                2. use an AT or PS/2 keyboard with an adapter that accounts for the electrical difference.

                The adapter that Chuck was referring to is one that accounts for the electrical difference.

                  That looks like the system I started this thread about. It looks to be a 5160 motherboard in a non-IBM chassis with an IBM PC top cover. It looks pretty clean, let us know more about it once you get it.

                    There are 2 ports on the back of the computer located above the keyboard socket. They are internally connected to a board via ribbon cable that has a Seagate BIOS chip on it. What the heck would that be?

                      Take a better look--the two ribbon cables sneak under the hard disk controller (with the Seagate BIOS on it) and connect to the multifunction/RAM board behind it.

                      My guess is two serial ports.

                        OK I was looking at the second picture and didn't see that.

                          I have to say that there is no differences in the electrical sinals when it comes to AT versus XT keyboards. The thing that makes AT keyboards and XT keyboards incompatible with each other is actually only the transfer protocoll, and some of the scancodes.
                          Current systems owned by me:
                          Vintage:IBM PC/XT submodel 087 ( 1983 ), [Kon]tiki-100 rev. C (1983), Compaq Portable I ( 1984 ), IBM PC/XT submodel 078 ( 1985 ), IBM PC/XT286 ( ~1986 ), 3x Nintendo Entertainement Systems ( 1987 ).
                          Obsolete:Commodore A500 ( ~1990 ), IBM PS/2 model 70/386 type 8570-161 ( 1991 ), Atari Lynx II ( ~1992 ), Generic Intel 486SX PC ( ~1993 ), AT/T Globalyst Pentium w/FDIV bug MB ( 1994 ), Compaq 486DX4 laptop ( ~1995 ).

                            In classing what is physical and what is electrical in an interface, isn't protocol in the electrical class?

                              I'd put it in the "ethereal" class myself.
