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.

        True, but from what I recall Future Domain had the same SCSI drivers for all their platforms, so I think it would work the same at the bios level, even if the bios version is different.

I don't remember if the SyQuest drives had such an option, but I wouldn't be surprised, especially on the older 44 and 88 MB ones.
        I wish I was where I could take a look on our SQ200 drive, but from what I recall, there are no such jumpers. Now, that being said, from what I recall if you boot a drive with a cartridge in it, it literally showed up as a hard drive. Only with the driver did you get removability.

          I have some SyQuest SCSI drives and cartridges somewhere; definitely 200MB, probably 88MB, 44MB and 1GB and 1.5GB. free for the price of a little gas...

              I was a bit let down that the Syquest Sparq drive was offered only in parallel port version. I've got one and i think I've had it out of the container only once.

                Sparq was also available in an IDE version though I think those only accounted for about 10% of production.

                Sparq should be treated as warning of how cost cutting could go too far. Most of the problems I have seen with Sparq were caused by the tray not inserting evenly.

                  From what I recall, the Sparq drive was basically introduced to compete with the Jaz which was doing much better than the Syjet 1.5gb due to errors on the cartridges. I could be completely off base here as my memory has faded quite a bit about those years, but living through them was quite exciting--Jaz, zip, syquest, mo, floptical, oh my!

                    Syjet was a follow on to the 270MB design. Originally about 650 MB which seemed reliable in prototypes; doubled to 1.3 GB when Iomega introduced Jaz; increased to 1.5 GB just before release and didn't work. Sparq was to be the ultra cost reduced drive that would have Zip drive appeal. Then there was Quest to get DVD equivalent capacity on a disk. With additional competitors like Avatar Shark and Castlewood Orb and the couple of roughly 2" designs, there must have been close to 20 different systems using removable disks between 1995 and 2000. Exciting unless data gets stored in one of the failure prone models.

                      Ah yes! All those others too!

                      We found in our analysis that by the time you ate the drive cost and got 1gb worth of media, the cost was less than a hard drive. But then hard drive prices started dropping as capacities increased. The removable drive in all forms was doomed once this paradigm shift arrived.

                        Don't forget the MO drives, such as the PMC Apex. I believe that one could boot from that as well.

                          Neat! Any driver needed for this?

                          I know I've still got a Maxoptix 4.6GB (2.3Gb per side) 5.25" optical drive and media. I just hope everything works as I still had some data on all that stuff.

                            The PM stuff (and probably the Maxoptix) was plain old SCSI, so you could set your controller to boot from it, I seem to remember. They behave like regular hard drives, although PM did offer drivers.

                            Right after the Apex, Pinnacle circled the drain. Those drives were horrible--they'd go out for seemingly no reason at all. PM was snowed under with warranty returns and were giving numbers like 6 weeks to 3 months before you'd receive a swapped drive (i.e. not you own, but someone else's repaired drive).

                              You know what--that drive we have is a Pinnacle Micro. I remember because the first one just stopped working for no reason one day and was replaced under warranty.

                                Sony SMO-S501 and SMO-D501 have a dip switch on the back that make the drive specify to the controller and operating system if it is a fixed or removable device.
