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.

    AT&T PC to Olivetti PC equivalent ?


    Olivetti made some PC for AT&T. So for example the AT&T 6300 is nothing else as the Olivetti M24 in a different color. Until now I know the following AT&T PC models, but not for all of them I am sure which Olivetti model it is originally:

    6300 -> M24
    6300 Plus -> M24 with 286-6 mainboard
    6300 WGS -> M240
    6312 -> M28
    6312 WGS -> M280
    6386sx/el20 -> M300-xx ?
    6386sx/el -> M300-xx ?
    6386/25 -> M380-25 ?
    6386/33 -> M380-33 ?
    6386E WGS -> M380XP9 ?

    Can you help me to understand better?

      I'm afraid I can't help because all I own are the 286 and lower models, which you've already identified (for which I'm grateful!).
      Offering a bounty for:
      - A working Sanyo MBC-775 or Logabax 1600
      - Music Construction Set, IBM Music Feature edition (has red sticker on front stating IBM Music Feature)


        Not what you're looking for, but I find it interesting -- Olivetti sold the AT&T UNIX PC (aka PC 7300) as the 3B1 in Europe (3B1 was only its informal name in the US):


          Jim or Dwight would be better qualified to comment than I.

            I am finding it strange that the trades didn't have short blurbs mentioning each AT&T announcement alongside its Olivetti counterpart. Paraphrased press releases used to make up half of Infoworld's content.


              You have to recall that this was a time just after the 1982 Consent Decree and what used to be Ma Bell was wading in unfamiliar territory. Around 1983, I recall trying to buy a 3B5 from AT&T. It was hopeless--get shuttled around among people who insisted that the only computer that AT&T sold was the 6300. Numerous requests for callbacks went unanswered. We leased a VAX system instead.

                I stepped also a little bit ahead, I found this: http://bitsavers.informatik.uni-stut...S_Brochure.pdf

                Accordung to the pictures and processor speed, the 6386-WGS should be a M380 (16 MHz desktop first version) and the 6386E WGS is the same as M380/T (20 MHz tower).

                First version of M380 and M380 XP3/XP4 are wide body desktop cases which have space for additional vertical mounted harddisks right of the floppy drive as can bee seen on the photo in the above PDF.

                But on the bitsavers server there is another photo showing an opened 8386 WGS without wide body, so the slim desktop chassis with just having harddisk bay under the floppy drive, similar to the older M28 / 280, so that one must be M380XP1 or M380/C, depending on cpu clock speed. I was trying to figure out that according to the BIOS bitsavers offers to download, PBVQ_1.13.BIN and PBVR_1.13.BIN, the version numer 1.13 is only mentioned with M380/C, but no mention of PBVQ and PBVR in the Olivetti pocket service guide. So I can not clearly identify this way.

                It would be interesting to know if AT&T also sold the other M380 series machines, and also about CP486*, LSX5010*, LSX5020*.

                * These three early 486 EISA machines could have been interesting for the history of Windows as they could be setup using an Intel i860 CPU as the 2nd CPU. With Windows NT 3.x Microsoft made a beta version to test that CPU, and I think the Olivetti/AT&T machines were the test target for that. But I have read about the results of testing Windows NT on the i860 that it was not a success, the machine was not running as fast as expected, and this was due to the bad / slow behavior of the i860 in conetxt change / task switch because of tooo long pipelines**, not good for a multitasking OS.

                ** Looks like Intel forgot these test results already when designing the Pentium 4.

                  Can you invite them to this discussion? I am unsure about their nicknames here.

                    I have never seen such a system. It should be very rare. It has exotic processor.

                        Trixter already answered.

                        Dwight Elvey , do you know more about AT&T relabled/redesigned Olivetti PCs?
