Forum 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.


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.


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.



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.


"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.

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.

    Tips on 5170 restoration?

    I have a 5160 that runs flawlessly, and a (hopefully) working IBM 5170 I'd like to get up and running.

    Currently, it will turn on, the hard drive will attempt to spin up, go "clunk" and then spin down. I'm assuming the drive is toast. It has two 5.25 floppy drives; after the hard drive it will check both drives. Then beep. Given this activity, we can assume it's working as intended, minus the drive that needs to be replaced? Also, one of the floppy drives won't latch - the dial is stuck. And the battery seems to have corroded, but thankfully it hasn't spread to the motherboard. And, finally, I dropped a screwdriver into the PSU and broke the cooling fan, so that'll need to be replaced too. Go figure the 5160 works without hesitation right!

    Ideally, what I want to do is replace the MFM hard drive with a small IDE drive, either fix or replace the floppy drive that won't latch, and install a VGA/EGA card so I can have more of a choice of monitors. So: What needs to be fixed, what should be replaced, and what upgrades would be recommended for a nice, but faithful restoration for my 5170?

    Are the floppy drives original? If not, there are some models of drives that will not let you close the latch unless there is a disk in the drive.

      * Replace the BIOS with the Quadtel or similar, so you can use other drive controller cards rather than the IBM MFM one
      * Then an 8 bit XT-IDE works fine
      * I've put a Trident TVGA-8900C in my 5170 for testing (It normally has stock CGA) and it works a-ok

        Welcome to these forums.

        Lots of IBM 5170 information at minuszerodegrees.net

        It is certainly a good sign, but you really need to get a display going to get the full picture (pun intended).

        My suggested upgrades for a "faithful restoration":
        * Assuming an IBM 5170 motherboard of type 1, if the motherboard has only 256 KB of RAM fitted, then adding the additional 256 KB.
        * Assuming that the maximum of 512 KB of motherboard RAM is present, but there is no card providing the RAM between the 512K and 640K addresses, then the addition of the 'IBM 128KB Memory Expansion Option' (see [here]).
        * The addition of a 360K floppy drive. See the bottom sentence of [here].

          How I have my 5170 configured:
          3Com Etherlink III ISA 3C509B-TPO ethernet (allows me to move files easily via FTP)
          I also have a Gotek which I use to easily boot alternate OS
          EGA w/ daughterboard
          256/512K system board maxed
          Memory Expansion 128K card
          Memory Expansion 512K card (switches set to start at 1Meg)
          5.25" drive
          3.25" drive

          I don't keep the Gotek in the system so really outside of the ethernet card, the system is period correct.

          I always felt I can never have enough memory

            There are lots of cheap 16bit ISA cards with an IDE/floppy interface you can get. You could attach a CD-ROM drive if you want. I use an old CD-ROM disk filled with old software to quickly move software to the hard drive. You can remove the CD-ROM drive when done.

            Make sure the current MFM drive setting are correct in the CMOS. The drive might still be good or need LL formatting. Cabling has been found to be bad several times on my systems.

            Have fun,

              Why would someone put an 8-bit IDE card made for the PC/XT into an AT? That's nonsense.

              You can use any 16-bit card with IDE (like a sound card) and, if needed, put the XTIDE Universal BIOS onto a network card. That way, you can also keep the original BIOS.
