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.

    Digital Equipment Corporation - MicroFiche Underground

    I'm starting this thread in an attempt to bring to the community, access to DEC's documentation, published on MicroFiche.

    This Underground is being started in the hopes that it will become a collecting point for others out there, like myself, who have original issues of DEC Microfiche sets.

    These sets contain incomparable engineering and service details on DEC products. Much of it, unavailable in any other venue, and in danger of being LOST forever.

    We are banding together, to transcribe to modern media and methods, the entire scope of knowledge contained in the various DEC MicroFiche sets.

    To accomplish this, we will do the following:
    • Register the fact of our possesion of Dec Microfiche sets with the Underground
    • Exchange Details of the contents or existence of various sets [whether or not we have them]
    • Obtain assistance [donations of equipment, software and funds] to accomplish the transcription
    • Support the output by distributing and hosting it on the internet
    • Accept requests for documents in the fiche library - to prioritize the transcription process.

    Please - If you are aware of any of these sets, let us know. If you possess one, consider donating or lending it to the Underground for the purposes of keeping it from being lost.

    This will be a non-profit endeavor, for the posterity of the computing industry and mankind in general. Let there be no more "Ancient Libraries at Alexandria" - Lost.

    P.S. - Feel free to PM me, if you have privacy concerns with your information or contribution.

    I will begin by submitting that I have the following:

    Blue painted steel lock-box container appx 4"x6"x10" Labeled:
    ID No. QBUS - 000371

    Includes the Booklet:
    Title: Using Your DIGITAL Microfiche Library

    The set appears unused, and complete. A quick scan shows XXDP sheets, Hardware Tech Manuals, User guides IPBs -etc.
    The index card is dated 1989.

    I need the donation or use of a high quality Microfiche reader, Microfiche Scanner, and software to take images of the documents and output them in PDF form.

    The documents contain various Diagrams mixed with TEXT, Source code and Images that will require the ability to perform OCR and editing of the documents to create useful searchable PDFs.

    Any form of assistance will be appreciated.

    I am aware that there are similar sets for UNIBUS and PDP-10 systems / products.

      I have this set:
      Plastic fiche box appx 4"x6"x10" Labeled:

      PC Microfiche Kit
      ID No. MD-PCKIT
      digital, Serial #0125

      The set covers PC100 (Rainbow), PC278 (Decmate II), and PC3XX (Pro) Hardware Tech Manuals, User guides IPBs, and same such for contemporary perhiperals (VR201, LK201, printers)
      The index card is dated March 1986.


        Microfiche Reader Donated

        The Undergound is now in possession of a Microfiche Reader.

        It's not a "Scanner", so pages have to be transcribed photographically, but it's a start and allows us access to the content. I suppose the first pages that need to be put online are the indexes.

        Here's a sample of a Rainbow 100 Tech Manual page 4-7. Clarity is even better than the attachment, which has been resized by posting here.

        Once we're a little practiced at it, images should be even better quality and PDFs will probably be OCRd.

          Vax/vms v4.0 src lst mcrf

          I'm posting this for one of our members, who contacted me about the existence of this set in his collection.

          I'm taking the liberty of doing this anonymously for him. I will update the post with his identity if he would like me to do so at any point. Until then, only the facts:

          cc 1984 Digital Equipment Corporation
          [hand written received 1-4-85]

          There are 439 individual microfiche in the set. Each fiche has something like 208 page images on it in a array of 12 x 16 pages. Each fiche physically measures 4" x 5.75"
          I believe this is a Collection of Source Code Listings for VMS v4.0. If this conjecture is correct, it would have been provided under license to institutions like Universities and significant DEC partner OEMs to fulfill the contractual obligation to disclose source materials, often present in major purchase situations.

          For Example:
          University of Queensland Computer Museum of I.T. [now defunct] had in their collection of documents, the "KL10 Tender response" which outlined the conditions of sale for that system. In it, DEC acknowledged that the University had license for all source materials and hardware documentation for any system or software provided by DEC. In addition, the University had access to DEC maintenance training and materials, only offered to DEC service personnel.
          Eventually, this library would have included sources for RT, RSX, DOS-10, TOPS-10, and VMS in addition to all Hardware Maintenance Documents and Materials. This latter, is more common for our members to possess.

          Indeed, the UQ Computer Museum WebSite had complete documentation for RSX and RT, along with many of the hardware documents for PDP-8, PDP-10 and PDP-11 systems available for download.
          Thanks to this member for taking the time to recover and secure these, and for contacting us here at the Underground.

          He indicates he doesn't have equipment to access them. An increasing number of our members are interested in participating in this capability once we have it.


            I have four boxes of DEC microfiche, which includes wiring diagrams, hardware manuals, etc. and an Informant II microfiche reader which I am about to dispose of. If interested or need more info, let me know.


              A private message is on it's way.

                Still hoping to hear back from you.


                  SejRane, I'm trying to find you. I'm guessing you may be related to somehow, a one time "Repair, maintenance, and consulting on all DEC PDP computer systems" company.

                  I have been unable to reach you via PMs here, and am thinking there may be something amiss with your email notifications settings.

                  If any site admin has access, please try to contact him via his registration email or contact info, to let him know of these attempts to respond to his post.

                  I would hate to see these documents end up being discarded.

                  Thank You


                    SejRane, I responded to your PM of Sunday September 4th, but there is no indication you've been back to see it.

                    Please check your private messages and let me know you've received it. Thank You once again for taking the time to find these a home.


                      Once again I would request a site admin to please contact Sejrane via his registration email address and let him know there is a PM waiting.

                      I can find no other means of connecting.


                        Thank You SejRane

                        I just sent this PM, and thought the community should be aware.


                        This afternoon I received your shipment. One carton containing four boxes of Microfiche totaling to a stack equaling some 30 inches.

                        This is a most generous gift, and we thank you profusely.

                        We will see to it that this legacy is preserved.

                        Most Sincerely,

                        DEC MicroFiche Underground
                        It will take me some time to catalog this collection, but in a quick scan I see it includes UNIBUS, QBUS, VAX, PDP-11, PDP-8, and PDP-12 elements. Diagnostics, Wirelists, IPBs, Manuals, Module Assemblies, and more.


                          Just a post to show some of our progress.

                          One of our members recently requested a copy of a TA11 [TU60] bootstrap from our Fiche set.

                          The following is what we were able to accomplish:

                          Although we still take too much time to prepare an image of a Fiche document page, we are getting more familiar with what it takes to produce legible output. We are hopeful to begin making complete Fiche Images available online in the coming months.



                            This is an absolutely fantastic project.

                            I know this is an old thread, but I wanted to give my big thumbs-up and kudos. I hope you're still active with it. If you need any kind of monetary donations for equipment or anything, please let me know. I can't contribute very much, but this is something worthy of supporting.

                              Status, Directions and needs...

                              Thank you for your kind words.

                              At this time, we are running the effort "on a shoestring" in order to be responsible with donations and resources.

                              Commercial equipment, in the form of MicroFilm / Fiche Reader - Printer - Scanners are available, but run $2000 ~ $8000 even on the used market. After analysis, it's clear they don't solve enough of the "whole problem" to justify the expenditure (yet). So we've been exchanging ideas with others who've also identified this need, and are in the process of constructing home-made instrumentation.

                              The following tasks have been identified:
                              1) Collect Fiches - too often rescued from the trash
                              2) Clean and recondition Fiches
                              3) Storage
                              4) Catalog and publicly list items in the collection
                              5) Scan and process Fiches into PDF format and offer the final result via the internet
                              6) Find a "Permanent Repository" for not only the collection, equipment and Fiches, but the output data.

                              There's a small book to be written on each of these tasks. Just listing them, prompts the imagination to realize how much is required to really preserve and keep these available, permanently.

                              My particular hope is that a method of scanning "Whole Fiches" into single, very high resolution images will be the key to the most efficient use and distribution of Fiches. To do this, a "large format Scan Camera", made by modifying a desktop scanner, is being considered.

                              If this is effective, we'll procure or write software to reduce these to PDF more or less automatically with a minimum of human guidance. (more with OCR) Then the software and Whole Fiche Images (WFIs) will be openly distributed to anyone wanting to contribute their time and effort (via the internet).

                              With so many Fiches here, and "out there"... getting "parallel participation" in a mass forum like the internet is the only practical way to get it all done in my lifetime. (and beyond)

                              A member is also experimenting by constructing a prototype "Precision Step and Repeat" platform for a reader in an attempt to make another imaging direction possible. This work continues at this time. If successful it will amplify our efforts, but still leaves the other tasks to be accomplished.

                              So much for the "Status"...

                              Donations - I would be happy to discuss contributions of any kind, with anyone who would care to PM me. Potential benefactors will be appreciated and considered individually, each with their own requirements and concerns. Some have donated only their time, others information, and still others more - as you can see from this thread.

                              Another Appeal for Materials:

                              Despite recent acquisitions - many, many, fiches are still missing from the collection. For example, I had really hoped PDP-10 and PDP-8 materials would be more represented among the donations. This continues to be my hope.

                              If you know of, or possess Fiches - please tell someone and leave instructions on what to do with them should something happen to you. We continually hear of materials that have been discarded during probate and estate processing. Even with clear written instructions, this could happen to your collection too. Families are frequently overwhelmed at these times, and "things happen". Please make it a priority to pre-establish and ensure your wishes are carried out - or just do it yourself.

                              Once again, thanks to the community. While the effort doesn't progress without monetary and material needs met, "moral support" is essential. We have to be in this for the "long haul" and keeping the topic in the public consciousness continues to make things possible as well as motivate us.
