Forum 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.

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.

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.

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.

"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.

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.

    Somehow the *.TD0 files have extra information in them. I have rebuilt both files K4836565.TD0 and K4836768.TD0,
    which includes new .IMD and *.RAW files along with the Original files. There is a folder with all the files extracted
    for the original *.TD0 files. The ZIP includes A Directory list and TXT document.

    Send me a PM requesting the updated Kaypro ZIPS.



      Thanks Larry; will do!


        It says your PM's have exceeded quota.

        BTW, do you have the original disk set that would have come with the 4/83? It would be nice to know which disks came with it and to have those disks!


          I sent you an email - thanks!


            I have a cpmish port to the Kaypro 2; if you're interested in a completely open source CP/M 2.2 port for the 4, I'd love to help. The 2 uses the ROM for nearly all functionality so the BIOS contains almost no code. I don't know if the 4 is at all similar, but if so, it should be very little work.


              hjalfi - I've seen your page before - looks pretty cool. I've looked at the CP/M binary that reports itself as II vs the IV and they are nearly identical.

                Yes, the differences between Kaypro II and Kaypro IV are minimal, and the bulk of the difference is in the ROM. But, big difference going to all later Kaypro hardware (2X, 4/84, ...).

                  I have been toying with cpmish for some time on the Amstrad NC200 and the Kaypro 4/83 (and my mini LCD Kaypro emu)
                  With the new alterations in cpmtools it seems I managed to create a bootable (and usable) image, it boots on the photo from a Gotek btw.
                  (I copied some original CP/M tools on the disk during image making as well)

                    I'd love to see a picture of your mini LCD Kaypro emu.

                      Here are some small pictures, the emulator runs on a Teensy 4.0 and drives a 480x320 color LCD (SPI), storage is on SD card and the keyboard is USB. It can do color too from within BBCbasic.

                        A late reply but I tried to duplicate some disks from the Gotek to the real floppy drive and it gives strange results like drive A sector 17 bad (no other texts, just that) but today I found out COPY.COM does not like being run at 5 MHz... At 2.5 MHz it seems to run fine. Strange thing is SSCOPY.COM does not misbehave like this... Weird..

                        Also tried Kaypro10 COPY.COM and it looks like it does something but due to the different hardware it always ends up formatting the Gotek image and not the selected drive. It also does not turn on the disk motor so hardware switching to the other (real) drive just activates the disk select light but no motor on and hangs..
