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.

    For those interested in the S-100

    FYI:

    Today UPS delivered three boxes containing a total of two Shugart 800s, four Shugart 801s and approximately 60 disks which clearly are from the S-100 era: They are all 8-inch, some have Micro Cornucopia Big Board labels and the like.

    I do not own an S-100 system: I bought the Shugarts; the disks were a throw-in. I'll try to report back shortly with an inventory of labels.

    The Shugarts are all dirty and two suffered damage in transit. There will be a claim to file with UPS and it will be a while before I am able to assess their operability. But I'm going to try; I've learned something by working on an 850 and I'll ask for guidance as necessary.

    I'll let you know what I find.

    Check that the metal part that the disk rides on is not swelled. If these were in a moist environment the pot metal hub can swell. If you put a disk on one of these it will damage the center. I've had to replace one to make one good machine out of two, once.

      Pot metal?! You mean these weren't machined from a solid block of titanium?

      (Thank you for your reply, Dwight. I hope you are comfortable during these trying times.)

      A couple of these were slightly damaged during shipment and they all need a good cleaning. If one out of every two works I'll be happy.

        I have inventoried the 60+ disks, all of which appear to be related to the Big Board II computer.

        A spreadsheet containing a list of the titles and any other information on labels is here:

          WOW! Lots of good files in the mix. What are your plans for Archiving all those floppy's
          without taking the chance of destroying them? Kryoflux, Catweazle, GreaseWeazle, DiskFerret,
          SuperCard Pro? Imagedisk or Teledisk? If you post on Google Drive or some server, I'd like to
          have a look at each IMD or TD0 file. It's fun to dig through all those Images.

          Most 8" Floppy's survive longer than the 5.25" Floppy's, which start shredding their Oxide onto
          the Floppy's Head(s). I know I waited about 10 years too long to backup my Radio Shack TRS-80
          Model 1's Floppy's on fresh media. Lost all the floppy's as each one deposited the brown oxide
          on my Floppy's head(s).

          On another note, I've got a version of PFM that I recovered from several Big Board Images, that you
          may be interested in. I sent the Source to Al at Bitsavers, but I don't think he captured and posted,
          the final update. I'll have to dig a bit to locate it, if you are interested.

            I don't think you can get teledisk anymore, so imagedisk should be the logical choice. All those flux formats are useless to people who are using real FDCs.

              As it happens, I do; from a 5.25-inch disk titled "Sydex Software Sampler" dating back ~35 years. But as Sydex has transferred license to another (anonymous, probably three-lettered) organization, and they have removed it from the market, I would hesitate to employ TD for this task for fear that Sydex might be held accountable.

              In addition, I wouldn't take any chances with these disks; Al has made the point that imaging such disks with unknown equipment is risky and I don't have anything but suspect 8-inch drives. In view of their obvious relevance, and potential significance, I move that we find someone who is both willing and certified to image them. I'll be happy to listen to your suggestions as to who that might be.

              Al volunteered Chuck for the task of imaging Displaywriter disks, but Chuck has his hands full right now. And I'd like to find somebody a little closer to home, in part because I am loath to risk shipping them again; they just came all the way from Portland, OR. Why ship them back?

                I have a fully tested and vetted 8" setup for SSSD and could image them with IMD. But I would not call myself "certified" not sure anyone is handing out 8" disk certifications these days, maybe the chair force?

                  Wow what a score I hope these disks can be recovered.

                    Hi CH - The disks are a great find. I'm all setup for reading and writing 8" disks also, with known good drives. It would be great if these could be made available to maxtherabbit or myself to image. I'd be happy to pay the one-way shipping costs if that helps, and to post the ImageDisk images online within 30 days. The downside is that I am in Australia, so MTR might be a better option? I have a BB1 and BB2 so pretty keen to see these images made available one way or another!
