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.

      Are the design files for the board available from anywhere I'd like to take a look at them if possible.

      Cheers.

      Phill.

        The full project will be hosted on GitHub, I just need to set up a repository and get the file structure cleaned up.

        Prototype boards should be in today!

          Boards arrived today!



          One slight problem -- KiCad apparently changed cathode designations on diodes and LEDs between the version that the rev 2 board schematic was created with, and the new KiCad libs. So the LED is backwards on the silkscreen. I also eliminated a discrete resistor by using a spare from one of the resistor packs. Other than that, it works!

          As you can see from the picture, the board house I do prototype runs with wasn't able to do selective hard gold for the edge connector. I'm getting quotes from a few of the production shops I've used in the past, including PCBCart, which I believe is who did the rev 2 run. I'll probably remove the unused ISA fingers to save on plating costs.

              GitHub repo created/current work pushed:

              https://github.com/glitchwrks/xt_ide

              Wouldn't recommend making boards from those Gerbers yet. There were no authors/contributors listed on the old KiCad project from the rev 2 board, which is what I started with. If you worked on it and would like your name added, please contact me, or send a pull request.

                That is correct. I'm selling the XT-IDE CF rev 3 cards from lo tech.

                I have however just 2 days ago built the full XT-IDE version from lo tech for myself:

                WP_20160514_001.jpgWP_20160514_002.jpg

                I can say that the PCB's are absolutely top notch. If someone is interested in the lo tech version of the full XT-IDE i can build a small batch of them. Price of course would be a little higher than XT-IDE CF due to the component count being almost triple and higher PCB cost too.

                Not to too my own horn but unlike sellers on eBay i don't cut any corners when making my cards. All functionality is to be included by installing even the optional parts. I believe that the functionality provided by the extra components (activity LED, slot 8, ROM address space selection) are really important. I like to use my XT-IDE cards on slot 8, as it allows me to save other slot for other stuff that won't work on slot 8.

                  That's probably something worthwhile to add to the XT-IDE rev 3. I'll see what that will take, tack it onto the current proto boards, and work it into the final rev 3 board.

                    Can you provide an estimate of the actual price for your finished card? I'm interested but I can't assemble one myself.

                    I asked glitch last week but he failed to respond.

                      I do not want to speak out of turn, but in an e-mail he sent me (messages have been falling through the cracks, so I don't believe he is intentionally being ignorant of requests) that the estimated cost of a fully assembled card was approximately $100 U.S.

                        Thanks, Daniel.

                        BTW, I made the request in a thread he had posted in, not in an email or PM:

                        http://www.vcfed.org/forum/showthrea...088#post413088

                        Maybe he missed that post.

                          Sorry, been super busy with this project, as well as day-job work! I must've missed your question. Typically in the past I've sold the rev 2 boards for $100 assembled or $85 if the buyer didn't want the UART bits. I'm hoping to offer the rev 3 to *hobbyists* at $85 each, assembled, but it will depend on what kitting up actually costs. I'd previously been running from stocks of ICs that were basically surplus from other day-job billable work so I don't have a solid figure on what the parts kits will cost right this moment.

                          Assembled of course really means "assembled and tested."

                            You say UART. Did this have a serial port as well?

                              The rev 2 board had a built-in UART for "bare metal" booting. I've had very few (none?) people request it be populated. As such, I removed it from the rev 3 board entirely. The UART was not usable as a COM port under DOS, strictly for booting. You could've used it with customized software, of course.

                                All this and the bus MUX timing has been solved already by my board which is available already.

                                The nice feature of the XTIDE R2 project is the serial boot, which can be used for file transfer between machines as well.
