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.

    iam also intrested in these XT-IDE controllers. Iam not intrested in the XT-CF versions.

      I am also interested in 1 or 2 of them. Isn't it possible to utilize a CF card with an IDE adapter if you went with just the XT-IDE adapter?

        Yes, I'd guess this or industrial Flash modules (DOMs) are the most popular uses for XT-IDEs.

        Quick update, I've almost finished with the new layout. Probably order a prototype run this week.

          I think the prototype layout is finished:



          Changes:

          - No UART
          - Removed some extraneous pullup/pulldown resistors
          - Sense is now ON == 1 for the config switches
          - ROM and I/O port options all switch configured
          - Decoding an extra bit on the I/O port, gives more possible port options
          - Single LED/connector option
          - Switch/Jumper descriptions added to silkscreen
          - Jumper header hole size adjusted for detent pin headers
          - Simplified settings for 28C64B/28C256 EEPROM selection
          - Swapped status/control latch for buffer (latch was always enabled, it was being used as a buffer)
          - Removed silkscreen around ISA connector and screw holes
          - All component values placed inside part legends, values placed outside
          - Capacitors optimized for axial bead type capacitors

          I ended up leaving the jumpers for the Chuck Mod option rather than permanent Chuck Mod, since the V1 BIOS doesn't seem to support Chuck Mod. I also left the 74LS537 latches as apparently I ordered a quantity of them a while back, so I've got plenty for kits. The board is somewhat smaller than the rev 2 boards. I also left the I/O decoder alone w.r.t the upper 6 I/O address bits.

            As per RetroHacker_'s request on #vc IRC, J1 has been moved so it's not possible to accidentally put the IDE connector in its position during assembly!

              Also prevents J1 being blocked if you decide to fit a boxed 40 pin connector for the IDE.

                Yup, much better to move it to the new position -- but that's one of the great things about an open dev process, this was caught before I even ordered prototypes.

                I also caught a clearance issue with the card bracket and the 74LS138, so everything in that area got nudged left and rerouted:

                    Would probably also be useful to have a jumper so you could have the LED on the front of the case.

                    Cheers.

                      The intent is to replace the LED with a jumper header when this is desired. I'll probably ship a Molex KK-100 2-pin connector in the parts kit so the assembler can choose.

                          Is the kit parts and pcb or parts only? Do you have any idea what the price would be, somewhere around 10-30$ or more?

                            Kit does not include PC board; however, if I find preorders with only a kit value filled in, I'll assume they wanted an equal number of boards too.

                            Bare board should cost between $10-15, parts kit will probably be $25-30. There's no financial commitment with the preorder, strictly for size estimating purposes.

                              I believe this change would require a modification to the BIOS and/or xtidecfg to allow for the additional IO options. Are the universal BIOS folks aware of this?

                              Love to see the XT-IDE project living on!
