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.

    Did I get a fake cpu?

    ebay auction: http://www.ebay.com/itm/130853000842...84.m1497.l2649

    Their picture shows on the 2nd line that the chip is a V30. The chip I got in the mail has the same model number but has v20 on it. Did I get boned? I don't really want to put it into a system out of fear it will kill the board.
    It is a mistake to think you can solve any major problems just with potatoes.

    I've purchased several items from UTSOURCE recently .....haven't have any problems with them.

    Not sure what the exact difference between the V20 and V30 is, but if you really wanted the
    V30 send them an email and see what they can do.....

      V20 replaces 8088
      V30 replaces 8086

        Try it--you won't kill the board; the thing just won't work. The labeling looks to be original--usually, the Chinese rebranding is not as finely detailed. FWIW, I have a V30 known to be good and it doesn't say V-anything on it. Just the 70116 line.

          Re the eBay auction.

          The "V20HL, V30HL 16/8, 16-BIT MICROPROCESSOR" is taken directly from a datasheet, a datasheet that covers the CMOS versions of both V20 and V30:
          http://www.alldatasheet.com/datashee...116HCZ-10.html

          Technically, their auction is describing both the V20 and V30 (CMOS versions). Because there is no, "Advise us which chip you want: V20 or V30", UTSOURCE don't know what they are selling. They've simply done an Internet search on the part number and found the datasheet.

            The V30 is a 70116; the V20 is a 70108.

            It's anybody's guess which this is--but I'll venture that it really is a V30.

              So either:
              1. NEC incorrectly labelled the chip; or
              2. Someone else incorrectly labelled the chip.

                Just installed it, apparently it is a real v30. I guess someone was asleep at the wheel over at NEC? Thanks for the replies! I can pretty much guarantee that if I had not asked, I'd fry a board. That's just how my life goes.

                Code:
                [UIDB69D11C1CB]MemoryTest=1217
                OpcodeTest=608
                VidramTest=927
                MemEATest=760
                3DGameTest=580
                Score=12
                CPU=NEC V30
                CPUspeed=8 MHz
                BIOSinfo=00F2092 COPR. IBM 1981, 1987    PARITY CHECK 1 (06/26/87, rev. 0)
                MachineModel=01FA
                BIOSdate=19870626
                BIOSCRC16=B69D
                VideoSystem=MCGA
                VideoAdapter=MCGA
                Machine=PS/2 Model 25/25L
                It does look nice next to the 8087. ^.^

                  I am VERY surprised by this.

                  Hard to see since Photobucket screwed up their hosting site, but my V30 looks like this in my model 25.

                    Well, very different date codes on my chip and ED's chip and LB's. But glad it worked.

                      Isn't it possible that these chips work as either a V20 or a V30?

                        I have bought from their ebay store & direct from their webstore... so far 4 out of 10 different processors I have bought have been fakes or remarks.
                        Some are remarks of same slower part... some are out right fakes.. markings & die
