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.

    Actually, the picture does not show a couple of more boxes of equipment that house a Poly-88 chassis (no orange cover), a Poly-88 card cage and power supply (less the transformer), two external 5.25" floppy cabinet/power supply with SA-400 drives, and a few power supply sub-assemblies for the 8813 and 8810.

    The Poly-88 chassis does not include the printer (serial) board or the cassette board. However, I found several of the printer (serial) boards and one cassette board piled in with the loose S100 boards.

      According to the owner (Chuck), there were over ten very serious Poly users in the Dallas area in the day. Chuck was an avid Poly fan and as each of the other Dallas area users finally gave up and went the PC/compatible route, they brought their equipment to Chuck because he didn't want to see it thrown away.

      From what I understand, he still has a number of PC/compatibles to get rid of as well. In his own words, "I've never thrown away a computer." So I imagine he may have some interesting early PC/compatible machines.

      Let me know if you want to find out more and I'll put you in touch with him.

        Hi Mike
        I suspect you should be able to use my tools to create the assorted tapes. I suspect I'd need to look at the directions I'd made. I recall they were not the clearest. They were intended for someone that was familiar with the cassette format ant the Poly88's monitor. The cassette interface requires a good recorder if you want to do the Poly-Phase ( high speed ) but the slow is just the Kansas data rate.
        If the tape recorder used a DC magnet ( actual magnet or head with DC ) it won't work with the Poly-Phase as this will cause too much distortion. Most cheap recorders ( like from RS ) used a magnet that dragged on the tape. This isn't too bad for most recording but causes too much distortion for the high speed format. You should have enough parts to put together a working Poly88.

          Good information - thanks! Actually, I already restored a Poly-88 and have both a working cassette, printer (serial) interface, and floppy drives for it. I probably won't be keeping the one I picked up with all this equipment.

            Wow that's a lot of Polys. If you decide to sell some let me know, I'd definitely be interested.

            I'm going to run my 88 on this GRI keyboard I got for now, until one without a keypad that looks correct shows up. I've seen 88s with both branded Poly and non keyboards.

              I’ll definitely be selling a number of them once I have a chance to start pulling together as many complete systems from this collection as possible. Depending on the number of viable systems that result, there may be some extra keyboards left. About half of them are without the number pad (all Poly branded).

              There are a number of documentation sets as well.

                The ones you have as duplicates, look to be 'System 88 Users Manual'. I've already got one but the one in the upper left look a little bigger that the rest.
                I have the text parts on disk for Word and Plan ( I think in the disk data I sent you a while back ).
                I only have one clean orange Poly88 covers but I think I may have one with a fan hole carved in it that you can have ( I'll need to check my storage ).

                  Sign me up for a monitor and a spare front strip if you got them after you take inventory and come up with prices. I travel to Texas quite often, so I can probably swing by on my next trip out there.
