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.

    CP/M System Disks - Please Read

    Although we're happy to help with enquiries concerning CP/M System Disks, we also recommend you try Daves Old Computers - Disk/Software Images website or the Usenet group comp.os.cpm if you require CP/M System Disks.

    Unfortunately in the passing of Don Maslin in August 2004, Don handled many of the CP/M System Disks which people could obtain from him, for more details check out Gaby's Domain people are welcome to contact Gaby if they wish to carry on with Don's Legacy.

            Is it possible to get a machine from the pentium days to run on CP/M? What is CP/M wirtten in?

                Besides CP/M-86, which was written for the 8086 archetecture, there are a number of good (free) emulators to run CP/M-80 on IBM-PC compatible hardware. Most of them may be downloaded from Gaby's site mentioned above.

                CP/M-80 was originally written in a language called PL/M, which was a port for microprocessors of a mainframe language called PL/I. Later versions were written in assembly language, IIRC.

                  There are also CP/M-80 emulators for CP/M-86. Personally though I'd go for an emulator and run CP/M through that (making sure you get an emulator which can handle CP/M well).

                  Isn't it true though that parts of CP/M were written in raw Machine Code (possibly Assembly) due to the amount of memory limitations or memory limitations of the Boot Sector. This wouldn't have been large amount of code, though code critical towards making CP/M efficent bootup and be usable. PL/M indeed would have been used perhaps in sections like the command line operation and internal commands.

                    See? I should always check the forum before posting redundant information I wasn't aware of this effort by Don (great job and unfortunate loss) but since Curtis is also trying to find some of these but I was going to repost the url above which is live. Dave's also here somewhere though I'm not sure if he logs in still. What this does make me increasingly aware of is how unfortunate it is when we can't share our archives online or consolidate them and they get lost on disk due to various happenings. Kinda puts a positive spin on the sharing of old applications to keep these things around for all to use, enjoy, and help preserve.

                    (Dumb question) Does the library of Congress hold software archives for copyright purposes? Do they or the proper authoritative entity ever release that software for public domain or retrieval?

                      It may not be a loss. Don's widow passed away recently and there's a very diplomatic determined guy holding discussions with Don's son about finally retrieving the archive.

                      Not usually--and note that in any case, the works would be under copyright until at least 2070 in most cases. While CP/M itself may be in a free-use open-source category, any accompanying code specific to a given system (such as the BIOS) would still be covered by copyright. After the GATT URAA negoations in 1978, specimen copies, proof of publication and copyright notices and registration were no longer required in the US. The rule of thumb is that a work is copyrighted unless it specifically says otherwise. The LOC would most likely not cooperate when it comes to works still under copyright.

                        Somehow or another I completely missed this thread!

                        In light of what Gaby and Dave have going on, I think any images I may pick up next weekend, I will send copies to both of them along with what I already have. That way there will be at least 3 places where stuff can be found.

                        Plus, we can hope the very diplomatic determined guy will get through to Don Maslin's son.

                          Well, I didn't get a blessed thing done on my archive this past weekend. Seems the Dell POS I was going to use has a bad floppy controller and somehow or another locks the 5.25" drive into 1.2 mode even if EVERYTHING says it's a 360K! Oh well, back to a generic no-name machine. They always work better!

                              Im trying to find a copy of CPM/3 for the Tandy Model 4/4p...
                              Altho I found a source from the site that has the emulator Im using, it is in ACE format and every winace Ive downloaded claims its 'broken'...

                              As long as I can find the system/bios file(s) I could probably connive a working system from it...
                              It neednt be in the original format... and could even be in a DOS folder.

                              Assistance would be greatly appreciated!
