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.

    A tale of two IBM PS/2 Model 77 systems

    Back in April of 2020 I wound up with a lot of IBM PS/2 systems and related parts that had once belonged to the Alberta Government.

    unfortunately all of the systems were in rough shape. Dust, dirt, and worst of all mice poop + subsequent corrosion from mouse urine. ewww.

    anyways the most complete and somewhat functional system was the PS/2 Model 9577 "bermuda"

    I say somewhat functional because the guy i got this stuff from fired it up, booted into windows 95 and then the magic smoke was let out and the system shut down.

    Thankfully it was just the hard drive that let out the magic smoke. (burned the board on the drive quite badly so the drive was cooked: well done.

    but the most important task for me was to clean out the mouse poop. so the computer needed a bath.

    success! put it back together and it was up and running perfectly!

    The system basically stayed in this configuration until I received a care package from Lorenzo @ NYCE distribution

    To make a long story short, Lorenzo and I worked out a deal for some parts to turn this system in an ultimedia clone.

    Unfortunately systems based on this case don't look very good with a CD-rom drive without the somewhat rare IBM CD bezel. and connecting an external scsi CD-rom drive is made difficult by IBM's use of a propriatary external scsi connected on the back. just can't win.

    Again I didn't take any *Good* in progress shots of upgrading this computer. But I wound up with an IBM CD-rom II with bezel, external scsi cable, M-ACPA card, and most notably the ultimedia front panel.
    (I also acquired an Action media II and 2.2gb hard drive from a local collector)

    the only part that wasn't as smooth was trying to create the ribbon cables from the ultimedia front panel audio controls. The cables were not included and i ended up choping up some old IDE cables to make them.

    Personally I think the system turned out awesome. I installed PC Dos 7 and windows 3.1 with all the ultimedia software for the action media II and M-Audio capture and playback adapter /A
    I plan on leaving the system mostly "stock" and as is with only IBM equipment. Something about an all IBM machine that I like.

    But with the release of TubeTime's Snark Barker MCA, I decided I wanted to try and find a Model 77 "lacuna" for a more high performance DOS/Win95 gaming machine. that I could "hot rod" without worrying about an all IBM system (since i already have the bermuda for that)


      After seeing a few Lacuna PS/2 Model 77 systems sell for LARGE sums on eBay. Especially the few Brand new in box machines, i figured they would be totally out of my price range. But one of the things I've learned over the years in this hobby is that making friends is a GOOD THING. One of the many friends I have made online in this hobby figured he had a dusty PS/2 model 77 lacuna stashed away. Lucky for me he did, and he was willing to sell it for a good price.

      After about a month over the Christmas Holiday, it arrived. (and thankfully in one piece. anyone else getting shipping anxiety with stuff like this?)


        Good work! Your stuff looks great.
        Surely not everyone was Kung-Fu fighting



          The system came to me with the two 2.2gb F/W 68pin SCSI drives Low level formatted, but the system partition had been restored which was nice.
          This system being a 77s (S for scsi) it originally would have had a Future domain scsi controller and a scsi narrow 50pin hard drive. However it's been upgraded with an IBM F/W scsi "corvette" adapter. (something they should have included stock if you ask me)

          (side note, the drives in this system are Quantum Fireball drives with IBM stickers and part numbers? if IBM had there own drives, I'm not sure why they would bother with re-branding quantum drives?)

          The Intel Pentium Overdrive @83mhz alongside the 256k L2 cache module gives this thing some serious horsepower. (16mb of ECC ram is nice)

          I found it interesting that this machine has a strange hybrid architecture. it uses the MCA bus for everything except the onboard S3 928 graphics which is an ISA/VLB card. (and needs some special IBM VLB TSR program to work)

          I installed windows 95 and have actually been using this system alot of the past couple weeks. It's very nice to use and feels much "snappier" than the model 77 Bermuda. The S3 Graphics is actually pretty good for games like Duke 3d, Doom, and anything else i've thrown at it. (substantially faster than the XGA-2)

          Now I await news from MonoTechPC for when he'll be shipping MCA snark barkers based on TubeTime's designs

            Thanks! Often times all they need is a bath...


              Very nice restoration! Congratulations!
