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.

    FS: Huge Pile of Old IC Sockets

    Pic says it all:



    This is a huge unsorted pile of old IC sockets. For the most part, these are crappy tin single-wipe sockets, DO NOT BUY THESE FOR MODERN PROJECTS! I suspect someone will want these for building up replica boards or for when you absolutely, positively must have correct-looking sockets. I was on the fence about just throwing these away, but I figure if someone can use them, I'll make them available. There's a mix of all different sizes, everything from 14 pin to 40 pin. Some have bent/broken/missing pins. This is a giant as-is pile for you to pick through. Picture of a few sockets pulled out:



    These sockets are awful, should not be used even in repairs in my opinion, but I know some of you like to reuse correct sockets, or experience that authentic 1970's "I spent an hour debugging this board and it's crappy sockets are the issue!" despair. $20 + shipping for the entire heap. Again, don't buy these thinking you're saving money and getting a good deal on quality sockets!

    All that having been being said, these appear to be and are, in fact, NOS sockets, aren't they?

        I believe so, they're certainly not solder pulls. Obviously not in factory packages. I have no information on them, they came mixed in with a large bin of wire wrap sockets.

          Just trying to be honest -- I hate them, in case you didn't know I won't use them on board repairs unless someone really *really* wants it, and acknowledges that there will be no warranty on the work.

            Don't buy them? They look like the sockets I've been buying off ebay for years.

              I'm beginning to question your sanity, or at least your judgement...

              What with machine-pin sockets being inexpensive, why, for the love of all that's dear, why?

                I've spent more money on sockets for my various projects than I want to think about. I don't consider even the lowest cost machine pin sockets to be cheap- many jelly bean 74XX series ICs can be had for less than the cheapest machine pin socket. Also note that some generic low cost manufacturer is making a variety of machine pin sockets that are a major pain in the butt to stuff, as the IC legs get hung up in the pin more often than not.

                That said, unless I'm building some kind of reproduction in which I'm willing to sacrifice reliability for appearance, I'll always use a machine pin socket.

                regards,
                Mike Willegal

                  Nowadays, when I'm looking for machine-pin sockets, I just purchase the single-row female headers in bulk. Allows easier access to the PCB area between the rows of a DIP and removes the need for stocking the various types (row count, spacing, etc) sockets. Looking for, say, 22-pin 0.400" sockets can be challenging.

                    ^^^ Yes, this. You can get "snap off" female headers in 20 and 40-pin lengths. They are awesome. DIY sockets of any width/size/length.

                    Edit: Looks like this is the best deal DigiKey has on what I'm talking about: http://www.digikey.com/product-detai...538-ND/3918942

                      Yup, I get them with wire wrap tails, too. You can make not only DIPs but PGA sockets, stacking connectors, et c. They're the thing to have for PC/104 boards, when you're using the full 16-bit connector and going pass-through (you can't solder the inner pins if you use standard PC/104 headers).

                        Well, since no one here has expressed interest, these are going to eBay.

                        EDIT: Auction link: http://www.ebay.com/itm/272453444939

                            Yes, not expensive sockets, but unreliable? It is all down to how you use them, the chips are best put through a pin straightener so they go in vertically. This is also true of turned pin sockets, PGA are fine, pins are vertical to start with.

                            I have disintgrated lots and lots of things, and recover socketted chips. In the years I have been doing this this type of socket has never had an insertion failure, whereas the turned pin type, and the double sided wipe version, have. The pin seems to catch on the top of the funnel contact and when pushed down, buckles and then makes a poor contact. This is really had to spot.

                            Also the contact between pin and socket contact with these sockets relies on pressure, a gas tight seal. This is not true with the other socket types that rely on precious metal. The snag now it that everything is getting old, a 40 year old chip into a socket. The pin tin has tarnished and the reliable connection is with these gas tight pressure seals, gold no longer works.

                            Don't discard them without realising that they do have their uses.
