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.

    If anyone is interested in collecting computing "firsts", it should be noted that the Columbia MPC was the first PC-clone to hit the market, beating Compaq by several months.

      I think the Columbia was the first luggable, but I'm pretty sure the Eagle PC was the first PC clone.

        No, the Columbia VP (luggable) came later. The MPC (desktop) models came out several months earlier. (I'll have to look up the dates, I don't have them handy right now).

        EDIT: Here's one quick reference:

        http://www.old-computers.com/museum/computer.asp?c=633

        ...and the VP model, dated 1983:

        ...and here's another reference, from Digi-Barn, which places the Eagle between the CDP and the Compaq:

            Of course, there are those who don't consider the Columbia to be a true IBM-PC clone, because the hardware wasn't exactly the same as the IBM. (Actually it was better). IBM only gave you up to 64K of RAM, the MPC came with 128K standard. IBM only gave you 5 expansion slots, the MPC has 8 (PC-spaced) slots. The MPC came with a video card, serial port and paralell port, IBM charged extra for thiers. Oh yeah, to really use the machine required the use of at least 2 of the five expansion slots in the IBM, one for video and one for a drive controller, leaving 3 available for expansion. The MPC only used one slot for the video card, the floppy controller was built-in on the mainboard, leaving 7 available slots. (The original 1600-4 didn't even need an expansion slot for the hard drive controller, it used a Xebec board that mounted on top of the hdd, with interfacing circuitry on the mainboard). All this, and it cost considerably less than the IBM! OK, well, there's a downside to the MPC also: It didn't include a cassette port, which was standard on the IBM.

              Here's another (partial) timeline, from the Obsolete Technology Homepage: http://oldcomputers.net/ibm5155.html

              1981: September - IBM ships the IBM 5150 PC Personal Computer.
              1982: April - Eight months after the introduction of the IBM PC, 50,000 units have been sold.
              1982: May - Microsoft releases MS-DOS 1.1 to IBM, for the IBM PC.
              1982: June - The first IBM PC clone, the MPC, is released by Columbia Data Products.
              1982: August - After one year of production, IBM ships the 200,000th IBM PC.
              1982: November - Compaq Computer introduces the Compaq Portable PC, the first 100% IBM compatible. It cost Compaq US$1 million to create an IBM-compatible ROM BIOS that did not violate IBM's copyright.

                Here's an interesting article on early PC cloning efforts that I kicked-up on a Mac webpage, of all places: (Warning: It's kinda long, but well worth the read).

                  Hmm. You learn something new every day! I always thought the Eagle was the first clone. . .

                  Thanks for the info!

                    Well, it depends on how you define "clone". By the strictest definition (exact copy), the Columbia doesn't qualify, but then neither do the Eagle or the Compaq. (I have a friend who subscribes to the "purist" definition, and we've argued this point in the past).

                      An exact copy would've required a non-obtainable license from IBM, right? (or the alternative mentioned, probable copyright infringing law-suit which is a poor choice to take only to become the first one)

                      I wonder which micro computer/video game system has had the biggest sales figure without any attempt to clone it.

                        I usually try to avoid using the term "clone" altogether, preferring "IBM-compatible" so as to avoid that confusion.

                          The classic test of compatibility used to be the Microsoft Flight Simulator. If that ran, the machine was a PC compatible.

                            Another legend from the time has it that a manufacturer would test-drive the 100 top-selling programs of that week to see if they would run. If 95 of them ran, then they could advertize thier machine as being 95% compatible, etc. (If they weren't satisfied with the results, they could wait another week and then try again with (hopefully) a different set of programs).

                              I never knew that. It's intresting how times have changed. It's been forever
                              since i've seen someone who uses a IBM desktop. I love there laptops
                              It's to bad they sold there name to the chinese.
                              Up untill now i considered IBM an American icon... It's almost like they sold a part of America.
                              If you don\'t know where you are going.. Any road will get you there.
