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.

    What are the top 10 rarest vintage computer bits you own?

    Just want to see what's out there. I've been sort of thinking about thinning my collection a bit to keep only the rare stuff. This is my list:

    1) Unbuilt set of 9 Mark-8 Boards (around 20ish Mark-8s exist and as yet I've not found another unbuilt set)
    2) SWTPC GT-6144 Video card (haven't found anyone with a site/blog that has one)
    3) Videobrain Expander 1 - (Mine is serial number 67 - I've only found two other people that have them so far)
    4) Tektronix Engineer's 6800 Board Bucket
    5) Digital Group Dual Phideck
    6) RCA Microtutor (Uses the rare 1801 cpu... I've seen 5 or 6 out there but there can't be that many)
    7) Unbuilt Netronics Explorer 85 kit
    Unbuilt Applied Technology DG680 CPU board kit
    9) Unbuilt Altair 680 motherboard
    10) Jupiter Ace

              Sheesh:

              http://www.sydex.com/durango/durango.html

              Both of my units are equipped with a hard drive. The earliest uses a large suitcase-sized SA4000 14" drive using HPIB to communicate; the other has a 20 MB Rodime 5.25" in place of the second floppy.

                BTW: If you have fewer than 10 rare items feel free to post whatever number you do have. I just want to see what else is out there.

                    How about rare items that you've had a part in developing?

                    I've got all sorts of rare tidbits; a 1401 core frame, a few "cordwood" modules from a CDC 6600, etc. But the Durango F85 is special to me, as the the Poppy (which I have been fruitlessly looking for for at least 20 years). Narrowly missed one being junked in Australia a few years ago...

                      Most of my rarities are probably mac related.

                      Tokamac IIfx, Daystar Powerpro 80mhz 601 + cache, Targa 2000 Nubus, Newer Technologies 68040/50 with 128K cache, Transwarp IIgs, etc.

                      I have some valuable items but I don't think they are rare. I mean a 5150 16-64k that is all original is worth something but I would not call it rare for example.
                      What I collect: 68K/Early PPC Mac, DOS/Win 3.1 era machines, Amiga/ST, C64/128
                      Nubus/ISA/VLB/MCA/EISA cards of all types
                      Boxed apps and games for the above systems
                      Analog video capture cards/software and complete systems

                        It would be nice if people posted pictures of their rare items. A lot of these things are so rare, I've never heard of them.

                          I suppose this is your "coolest" rare item.

                            I have a few other things I've thought of:
                            M20 Olivetti ( not to be confused with the M24. This is a Z8000 machine. Not that rare in Europe but rare in the US )
                            QuikLoader for the Apple IIe ( puts several disk file images in EPROM for instant load. Require use in slot3 so may interfere with other boards requiring slot3, like SwiftCard )

                              no idea how rare...
                              ... but these are what I have

                              1. IBM pc/server 500 with P/390 board (1995 is this vintage?)
                              2. IBM model 10 card punch
                              3. SWTPC CT64 VDU
                              4. EIA TR10 Analog Computer (is this a computer)
                              5. SWTPC Video Boards (plus late model SS50 machines. Whilst these are not as nice as the early machines I think only a few survive.
                              6. HP7510 Film Recorder.

                              Nokia badged IBM 3270 compatible terminals?

                              I did have an Atari TT030 and a Large Roland Plotter but these went to others..
