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.

    Safe way to insert v-20 in 5150 without bending the legs?

    What is the best way to insert v-20 in a 5150 without bend ring the legs?

    #2
    Very carefully

    If the legs are bent i generally use a IC socket - Long nose pliers and or hollow needle, Get the legs aligned so they fit the socket perfectly, Place the IC in the socket in your 5150 and before pushing down make sure all legs are where they should be in the socket, Use a magnifying glass if needed. There are IC leg straightener tools around but i never bothered buying one.

      I'm being a bit lazy and leaving the motherboard in situ in the 5150. After a few goes with a pliers I got the V-20 seated.

      Might buy one of those straighteners. 5.00 on eBay.

      Edit: Going to tackle glitch's XT-IDE kit next.

        Without pre-bending the legs... what I do is use both hands to firmly hold the two ends of the IC (and avoiding touching the pins). Get one row of pins engaged in the socket, then push the IC sideways until the opposite row of pins will engage into the socket. Only push the IC fully into the socket after you have verified all pins on both sides of the IC have engaged with the socket.

          I just go ahead and bend the legs, using a pair of smooth-jawed pliers. Doesn't hurt a thing.

            For long DIPs if I don't feel like digging out my straightening tool I will just place each row of pins against a flat surface and roll the chip

              Smooth-jawed needle-nose pliers are about as gentle as one can get. Although I own pin straighteners, the pliers do a better job.

                  I put the IC on it's side on a flat surface, and push down while rolling inwards a little. Then repeat for other side.
                  Test fit, if still to wide, roll more.

                  Only takes a few seconds and always works flawlessly for me.

                    I hopped into this thread to recommend this exact thing. The only thing I'd add is when you do the rolling action try to center over the thicker ends of the pins so you're basically re-aligning the "whole" pin. (IE, you're changing the angle of the existing bend where the pin emerges from the chip body instead of just bending the thinner part that actually goes into the socket inward.)

                    On the needle-nose pliers suggestion: that works too, but don't be a bonehead and accidentally snip off one of the end pins because it goes past the flat part of the plier into the wire-clipper part near the hinge. Not speaking from experience here or anything.

                    (Or, yeah, maybe I am; managed to do it to a flash ROM chip. I fixed the chip by seating it in the socket, sticking a bit of lead cut off a resistor or capacitor into the socket hole where the cut-off pin belonged, and soldering it to the stump of the pin. Works fine, isn't exactly attractive.)

                      And if all else fails, there's always this:

                          Seems to me that a bit of aluminum U-channel with a hole or two in the top could accomplish the same.

                            I second that! Funny enough -- just did that with a V20 two days ago!

                              I will have a go with the rolling method for the next one. Found my chip extractor.
