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.

    JDR MCT 8-bit IDE controller

    There were some discussions about the JDR MCT 8-bit IDE card in another post awhile back.

    This card was originally marketed by JDR Microdevices under their brand Modular Circuit
    Technology back in the late 80's/early 90's.

    I purchased one of these recently (on the auction site) and took a couple of pictures. The card
    only works with drives up to 528 MB but has a few unique features one being an additional
    interface on the back to attach an external IDE drive. I'm sure the soon to be released 8-bit IDE
    controller will blow this one away......

    anyone else have one of these cards ?

    I use to buy stuff from JDR and thought they made a 8bit IDE controller but I have never seen one anywhere in recent history. Look like a great find. What did you have to give up for it?



      $36 shipped , which seems a bit high , but I had been looking for this card for
      some time so I couldn't pass it up. It even came with a one year warranty, and the original
      box, packaging and documentation. I have a few old JDR catalogs laying around which show the card
      ....originally sold for $79 back in the early 90's.

      There's more info on the card on the JDR web site at this link :


        I think Jameco also had an 8-bit IDE controller, but the number escapes me at the moment (JE-xxxx).

          Hmm, I also have an old Jameco catalog somewhere, will need to check that out


            $36.00 shipped was a steal, IMHO.



              Does anyone have a scan of the full manual for this card? All I can find is JDR's ad for it, which doesn't list the jumper settings.

                About 13 years ago, 2008, you couldn't find a 8-bit IDE anyware. Maybe not rare as they say, but definitely scarce, hence the forum's own XT-IDE. Yeah, it's been that long.

                Surely not everyone was Kung-Fu fighting


                  I have the manual, not a lot of info there but here's a few pages ......

                  EDIT: The images are out of order ...... can't figure out how to reorder them

                    Thanks, I copied the images and save them for future reference. That's a card I'd buy if it could be had a a reasonable price. I've always like most of the MCT line of cards.

                    11 years between posts, cool...


                      I just got one on eBay for $12.99:



                        You got lucky. "Genuine Rom Bios CI-1020 UC960029 PCI Card Desktop PC" I would have never found it with that description. PCI, card LOL.


                          "-Tested and Working condition"

                          Somehow I doubt that (the tested bit that is - I'm sure it works fine).

                          vwestlife, would you mind dumping the BIOS when you receive the card? Perhaps I can add support for it to the XUB. BTW, it's funny how the manual says JP4 is used during "factory testing" when it's very obvious that it's used for selecting the ROM size.
                          Looking for a cache card for the "ICL ErgoPRO C4/66d V"


                            I'd also be interested in getting a copy of the BIOS to see if it's a more recent version.

                            My card's BIOS contains the following string:
                            Centos CI-1020 ROM BIOS Version 3.30for ISA 286, 386SX, 386DX, 486SL, 486 System.
                            (c) Copyright 1990, 91. Centos Inc. All rights reserved.


                              mikey99 A copy of the BIOS from your card would also work for me.
