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.

    PC 5140 Convertible - Permanent Storage Options?

    Were there any permanent storage options at all ever available for the Convertible? IBM or 3rd party?

    Thanks,

    There were a couple of hard card slices announced in 1986 and the hard drive adapter slice described http://www.vcfed.org/forum/showthrea...PC-Convertible which seems to a variant on the Diskit available for Tandy and PC Jr are the only items I can find records of. Edit: SPI's device was renamed the Quickbrick and there are pictures of it in Portable 100 magazine.

    Third party only and scarce.

      Well, there is THIS parallel port SD card... thing.
      Obviously not from the same time period, but if you can find an LPT slice, and you just want something better than floppies, you can use it for storage with that driver and a bit of wiring.
      Current favorites: IBM 5160 (EGA+Hercules+PGC, 8 floppy drives, XT-IDE), DCC D-116 (Nova 1200 clone), ASR 33 Teletype, PDP-8/I (lots of issues, restoration underway)
      Wishlist: IBM 5161 (expansion chassis), Diablo 31/RK02/RK05 or equivalent, Data General equipment, and the meaning of life.

        I would sure like to find a hidden stash of the mating connector for the Convertible’s bus, but I haven’t even been able to find anything with the same pitch.

          Why I Asked (if anyone wanted to know)

          Years ago I was forced to downsize living quarters and if you're someone who has been collecting vintage technology for a long time, it is not conducive to keep it all in smaller living space (unless you are using system units to also serve as furniture, right?) I still have a 5150, 5161, 5153, and the IBM rebranded Epson printer. It's kind of my pride and joy, took a long time, and a lot of money to put together, as I'm sure many here have similar type projects and experiences. The late Tom Chavez (bettablue) and I would spend a lot of time e-mailing back and forth about our collections and our cornerstone machines. He had two 5150's and 5161's, his favorite he called Alice.

          Anyways, as I'm debating about selling my cornerstone piece, I still want a piece of vintage from the period that takes up less space. Ideally, I'd like a 8525, had one years ago, a color unit. Even with two ISA slots, I could eventually find again the external 5.25 adapter card and use a XT-IDE/CF in the other slot. Those are really hard to find, complete, and working, but have been seeing a lot of 5140's... if there's a fixed storage solution for the 5140, that'd be pretty cool, but as you've said, few and even farther between for the 5140...

          I appreciate the input guys.
