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.

    Second batch of boards just arrived! If you ordered something and were told that they hadn't come in yet, they'll ship tomorrow or Saturday.

    Just ordered 100 more bare boards, should mean that boards, kits, and assembled units are available for a while

Some of the assembled boards use 4.64K, some use 10K, some use 12K. It's just a pull-up so the value is totally noncritical.

    Likewise, the 470 Ohm resistor is just a current limiter for the LEDs, though all of the kits have shipped with 470 Ohm resistors. Some are 5% green metal film, some are 5% tan carbon film, and some are 1% blue metal film.
    Ok, thanks glitch!, good to know that there's such a wider range of values accepted.

    Btw, great work with the v3!, is working nicely with a 1GB CF. No real problems (I struggled a bit with the flashing procedure at first) in the PC-1640 until now.

    Just wanted to note that we're in the middle of moving out of our apartment and into a house -- I'm trying to stay on top of shipping but it may take as much as 3-4 days for me to get your package out. I've got all of the XT-IDE rev 3 stuff set out so it won't get mixed in with the general packing/moving.

    Edit: I answer myself, BIOS is obviously empty
    Just a minor problem, the kit comes with a pair of 12K resistors when suposedly (by looking the PCB), 10K resistors are needed. Is it intended?.

    Kind of, but for writes as well. There is optimised REP INSW code for V20 equipped machines in the XUB.

    It's certainly green, but how's it faster? Meaning the default "Chuck Mod" mode?

    Of course, the important thing is that it works and that solves our problems but mine was just a joke but I see that in many if they are taken in bad...

    Heheheh... sounds like you have an arthroscopic camera installed inside your PC.

    Let me get this straight ..

    8-bit IDE Adapter PCB

    The card's cost is $ 8
    The cost of all the components is 20 $
    Shipping cost to Italy?
    To Italy I must also calculate customs charges
    All the chips are to be programmed or are already planned?

    Total 28 $ + shipping ??

    P.S:Robin is right, if the board is green I prefer 1000 times more
    If the card is blue on a pc of the 80 it is a punch in the eye!

    Received here, all fine and safe of course.

    With a bit of luck and time I'll finish the assembly today. Btw, the 28C64 has any BIOS flashed or is it empty?

    Edit: I answer myself, BIOS is obviously empty
    Just a minor problem, the kit comes with a pair of 12K resistors when suposedly (by looking the PCB), 10K resistors are needed. Is it intended?.
