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.

    Hmm...could be several reasons. Could be that the disks are not even boot disks. Could be other reasons too, some of which are mentioned here. On that same page further down, there is a link on how to make a boot floppy for these CP/M machines (assuming you've got the right hardware).

    Hopefully that will help.

        Ah, then I would start with the power supply. Take the machine apart. Check the drive is plugged in and the cords and cables going to it haven't come loose. If there were no loose or unconnected cords then check the Power supply unit is providing the right voltage to the mainboard.

        If you do a google around you'll find technical manuals on the Osborne which show you how to take it apart. it's fiddly but doable. Be careful of main voltage around the PSU when you're testing. Also, take photos of the connectors etc as you disassemble because it's easy forget what when where when it's in a dozen parts!

        Does the screen image have a solid picture? Or is it wavy and jagged. Does it get far worse when you press return to boot?

              I replied to the video in the comments, what was I listening for? I heard some high pitched sounds like voices near the end, but that was all.

                Power supply is normally silent. About the only thing you should hear is a beep on power up and then just drives chugging along. Unless a fan has been installed. And judging by the picture, yours doesn't have a fan.

                One thing Tez didn't mention is the power to the floppies is via the ribbon cable! So make sure and DON'T put the cable in upside down. Ask me how I know...

                You didn't mention if you got the boot up screen or not. Yes/No?

                If you're not getting anything on the video and no floppy action and a high pitched whine (so glad I've lost that part of the audio range!), your problem probably is power supply.

                I do have an extra original power supply if you need it. Your profile doesn't say where you're from, but the power supply is pretty small and shouldn't cost too much to ship.

                OR you could shoehorn a small more modern, more powerful power supply in the case. It's tight, but it can be done. Just be careful of the voltages going to the right place. Again, ask me how I know...

                Good luck.

                    When you press enter the drive should immediately try to work and if it fails to boot it will spam the screen with "BOOT ERROR".

                    Seeing as your system didn't even register the enter key being pressed I suspect something is up in the keyboard.
                    I knew someone who had the opposite problem where the system would instantly spam BOOT ERROR because the enter keyswitch was jammed down.

                    Edit: I didn't see the post above me
                    Well I don't see the drive activityl light turn on and I can't hear anything over that racket.

                      You say "i get a display on the screen i just can't seem to get the drives to do anything when i hit return the floppy light comes on quik when the system beeps on power up the drives don't spin up or anything just that"

                      Do you mean "i get a display on the screen i just can't seem to get the drives to do anything. When i hit return the floppy light comes on quik. When the system beeps on power up the drives don't spin up or anything just that."

                      Or do you actually mean.... "i get a display on the screen. I just can't seem to get the drives to do anything when i hit return. The floppy light comes on quik when the system beeps on power up. The drives don't spin up or anything just that'."

                      See how important the punctuation is when trying to convey meaning in text.

                      I've just watched the video and I think you mean the latter i.e nothing happens at all when you hit the keyboard. That suggests to me a keyboard problem. The machine isn't registering the Return key is being pressed.

                        You could always open up the keyboard and measure that the cable is in working order (Measure the leads one by one for continuity with a multimeter set to the "Beep" setting) and check the keyboard connector on the Osbourne for dirt or corrosion.

                          I couldn't agree more.
                          I'll skip right over some posts if I can't figure out in the first read, the information that someone is attempting to convey.
                          I'm not about to spend two minutes reading a post trying to decipher it, when the poster only spends 10 seconds writing it.


                          Osborne keyboards are a real problem - I've been through a few.

                              NOW I see where you said you get the display. My bad on that one.

                              Anyway, like the others said, sounds more like a balky keyboard.

                              I may have a spare keyboard if needed.
