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.

    Amstrad PPC 640

    Can someone tell me which forum I should be on to discuss this laptop? I'm new to the forum and in typical fashion, trying to determine a value on this? Is it collectible or just an old computer that is not of value to anyone?

    Some details: The manual says it's a 1988 or thereabout, it does work, it has the power source, the car lighter source, the mouse, the manual, 3 discs, and the carry bag. Two pics attached.

    Some background information: In 1992 while a company operations sergeant in the Army, a co-worker saw how I was struggling to maintain everything without a computer (nobody in our battalion had them). We had maybe two electric typewriters in the unit. He asked me if I wanted to use this. He showed me how and I did for about two years. It was nice to be able to save documents and edit them. That sounds so archaic but that's how it was. When I came in the Army it was manual typewriters with carbon paper and whiteout.

    Anyway, if you can help me out, thanks!

    If eBay sold items are any guide you might be able to get a couple hundred bucks out of it. That seems to be the going eBay price these days for a working "antique" PC. (The Amstrad PPC640 probably isn't anybody's idea of a "classic" or in any way rare or historical, but it looks fairly nicely preserved and I'm sure someone would take it off your hands.)

        I think its a classic. It was the right price in the UK. You didn't need a monitor. It folded away nicely and didn't take up any space. You could get it with a builtin modem. I had one with a 20Mb hard drive.
        My kids learnt computing on one connected to my old Phillips CM8833 (perhaps 8832) which was an Analogue monitor I bought for my Atari ST but which did CGA as well playing CGA games.
        If you google some one has added back lighting to the LCD display making it usable.

        Two have passed through my hands recently but I gave them both to a Museum so I can't comment on value. It also depends on where you are. I would think that in the UK there would be more demand because there were many sold there, so more nostalgia. Its always worth popping a country and state in your profile so we can see where you are, because often local solutions work well..

          I plugged it in today and the volume works, screen contrast works, you can hear the drives working with a disc in each drive but other than the contrast, I can't get anything to show up on the screen.The last time I used it, 1994ish, it worked just fine. Maybe I'm doing something wrong.

          Initially I started it with the discs in each drive (this is where they were when I took the computer out of the closet). Then I read the manual and it stated to do the initial start with no disc, so I tried that with no avail.

          Do LCD screens go out with no use?

          Any advice?

            You need to check how the DIP switches are set - it may be configured for an external monitor rather than the internal display.

              Thank you. I'll check that

                They did sell them in the US, but as I recall their initial price wasn't particularly attractive compared to smaller and more portable machines like the Toshiba T1000, and I think a substantial number of them ended up being liquidated by one of those big mail-order surplus outlets after an initial poor retail showing. They were common enough that I've seen a couple in the flesh, which were probably ordered at the closeout prices.

                (Amstrad definitely did *try* to make it in the US, as I recall several department stores tried carrying both the PC1512/1640 lines and the PC200 desktops for a year or two, but later models are much rarer.)
