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.

    Oh man! This is what I get for not paying attention to every forum to which I belong. If there's a chance that one of those boaeds is still available Id give it a good home!

      Following an email discussion with John Walker (author of MDEX and NOS, founder of Autodesk), he created a few pages on his website about Marinchip:
      http://www.fourmilab.ch/documents/marinchip/

      The photo of the I/O board is credited to me, but it is really Jim Hearne's. I'll write to John to get that corrected.

          I've googled around and think I've done my due dilligence, so I'll go ahead and ask: has anyone in the States done a run of the mini-cortex PCBs? I'd love to snag one, but I've never ordered direct from a manufacturer (and I don't need 20).

            Mini-Cortex PCB - send me a PM.

              Hello everyone,

              Cortex Mk1 owner here, I built the machine when it first appeared. After many years in storage in the attic I tried it this week but unfortunately it no longer fires up.
              My machine is very basic due to lack of funds at the time, it has the cassette interface only.
              Are there any resources that might assist me with fault finding ? I looked through a lot of this thread but it takes a while
              What I've tested so far;

              1. The power supply is all okay
              2. 12MHz clock pulse is okay
              3. continuity of chip pins to PCB are okay

              Currently the BASIC LED is constanlty ON
              The MEM LED flashes once after power is switched on
              IDLE LED is OFF and does nothing
              RUN LED goes OFF when REST button is pressed then comes back on very dim.

              Any help would be very much appreciated.

              Doug.

                Hi Doug,

                Do you also go by the name of Thomas, who sent me an e-mail on exactly the same subject? Or has the unseasonably warm weather got two old Cortex owners to drag their machines out of their attics?

                I'd suggest the first step is to test the DRAMs, as they seem to go bad fairly frequently. If you want to send me a PM, I'm happy if you want to post your DRAMs and EPROMs to me for testing in my Cortex, to help isolate the fault.

                  Stuart,

                  Many thanks for your message, yes it's the same person, what's the chances of two ?
                  I sent you an email because I thought my first post here had failed to pass the "Moderator Test" having taken several days to show up.

                  That is a very generous offer to test my chips and I will send you a PM now.

                  Many thanks
                  Doug.

                      Hi folks,
                      Just fetched my Cortex out of storage, and to my delight she still boots up just fine.
                      I have initial version, with the twon 5.25 disk expansion installed. I've yet to find any of my original disks for it though...
                      Anyone out there got any of the expansion boards that were briefly available - e.g. the memory expansion, or maybe a VGA style connector for modern day monitors?
                      I'd like to resuscitate this and maybe even build a few add-ons for it.
                      Thanks,
                      Dawn

                        Hi Dawn,

                        Glad to hear another Cortex is out there alive and well. Take a look through this thread to find out some interesting history on the Cortex along with hopefully some answers to your questions. More or less all disks have survived and are available in one form or another and it is possible to create disks from your Cortex with the use of a PC and a couple of utilities.

                        Most of us on this forum get notified when someone posts something but for some reason or other, new posts can take a few days before this happens.

                        All the best,

                        Dave.

                          Gosh, a new message!

                          What Dave said.

                          Plus for a VGA style connector, the F18A video board can be used with the Cortex (http://codehackcreate.com/store#!/F1...176/category=0), but they're currently not available pending a new version with an HDMI connector.

                          Comment


                            Several years ago I wrote a manual on how to use Dave's WinCortex emulator and the PC<->Cortex transfer utilities. To make a boot floppy and to transfer disk images from the PC to the Cortex, see section 3 of http://www.stuartconner.me.uk/powert...ft%200.01).pdf.

                              That's very kind of you Stuart! Been meaning to do that for years...

                              I'll have to put Version 2.1 up which is needed for NOS. I'll try and give the manual a read and see if there is anything you can add (e.g clicking a 'floppy drive' can be used in addition to F1-F4, and pressing CTRL while clicking a drive ejects a floppy image).

                              Dave.

                                Yes, this thread will give you a lot of useful Cortex data. A lot of the available documentation can also be found here and on the WHT site.
