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.

    I've been digging because something doesn't smell right to me. According to the documentation I could find for the 3000 it shipped with:

    CURRENT BIOS ROM Version: 01.03.03

      The Phoenix BIOS copyright date is 1988, which post-dates that revision of the Tandy 3000. (The original "3000 HD" with the 8mhz/512k motherboard as pictured was replaced in the 1988 Tandy catalog with a 12mhz version that took 640k on the motherboard, was listed as having nine expansion slots instead of ten, and had a keylock on the front.) It does seem very unlikely that's the original BIOS chip.

      It's possible they replaced it to support additional hard disk types or something.

        Trying to reverse that hack job is going to be more trouble than it's worth, I think. Where would you even get the correct BIOS ROM from this many years later? That's probably why it throws errors on boot. The BIOS is not completely compatible with the motherboard.

          I managed to pull mine out, seems to "boot" up or rather attempt to. Floppy is never accessed, but small diode at lower left front comes on briefly, I think it's for hard drive activity. Tomorrow I *may* be able to find a suitable monitor and video card combination that may shed some light on this situation. I think the only working monitor appropriate to this is a Taxan 635? Iirc. Don't even know where a vga card is, that would be the easiest solution.

            Mine is in storage, or I'd double check myself. I'm glad someone else has one that can check. It's really hard to find other people who have one of these or the 4000 & 5000 models. If 3000's are rare, 4000's and 5000's are practically non-existent.

              I did a search and apparently an NL was sold for 100$. It didn't turn up in my saved searches email. I never knew that model existed and it doesn't have any particular interest to me. But as I said they don't turn up very often, but never seem to command excessive value. A 3000HD or HL all decked out may fetch a tidy sum though.

                The HL and NL served the same market and sold for similar prices when new. The NL is the newer of the two and is an updated version of the HL with a faster processor and more RAM. It also introduced 3.5" floppies to the line. A later update to the NL motherboard put a VGA chipset onboard to free up a slot. The HD has always been harder to find because it cost $4299, while the HL was $1699. You usually see one HD for every 4 or 5 HL/NL machines. That's been my observation, anyway.

                  In reality I always wanted an HL. Then my affection waned and I saw an HD as the thing to have. Really REAALY wanted a discrete logic version though.

                    I have a Tandy 3000 Diagnostic Disk (IND format) if anyone is interested. It was in a bunch of floppies I picked up the other day and I just archived it.

                      Someone way overpaid for it. About $400 shipped, and don't forget ebay charges sales tax at checkout now. The keyboard might sell for that on a good day, but sorting out the problems with the machine itself isn't worth it. In that condition, I don't consider it as anything other than a parts machine.

                        Wow...$324.52. Anyone here the winner? That was about twice my max bid. I would be curious to know the deal with the BIOS identification.

                        The first computer we had a home for the family was a Tandy 1000SL. A number of years later I was online with the Delphi online service, and someone in the Tandy group was giving away a 3000HD, so I acquired it for the cost of shipping, and thus was the first computer that was truly mine. Came with a CM-1 monitor (had issues, ugly display, but it worked - wish now I had kept it anyway). Upgraded it in various ways and eventually upgraded into a custom 386 and went on from there. The 3000 got set aside, and ultimately the battery leaked, messed up the motherboard a bit, and turned the case into a rusty mess. I tore it apart some years back with the intent to try to clean up the rust and see if I might be able to get it going again, but never made it any further. Probably need to sandblast it or something...probably should do something before it rusts away to nothing, even if I can't get it going again.

                        If anyone has a spare 3000 motherboard (or whole computer) laying around they want to sell, please keep me in mind...

                          Everything seems to be going way high these days, at least in my opinion (for what little it is worth). Wasn't all that long ago you could pick up an old computer for $50 shipped...though shipping prices have certainly gone up a lot too.

                          As for the keyboard, if you do a search on completed items, there is a listing titled "Private Listing 1 (Tandy 3000 Vintage Keyboard)" that sold for $345. I wonder what the story is there, I can't imagine a 3000 keyboard is anywhere near that valuable! But if it is, someone got a good deal on this one since it came with a keyboard...

                            Don't forget the $78.10 for shipping plus whatever the buyers state sales tax is. It could run as high as $425 total before it's all over for a machine with a questionable history that will probably continue to have compatibility issues until the original BIOS is restored. It's not worth having at that price.

                              While it still boggles my mind that a dirty 286 selling for over $300 isn't particularly noteworthy these days (dang, do I wish I had the contents of my garage circa 1998-ish to sell right now...) I don't think there's that much wrong with the machine. I doubt the memory error has anything to do with the replacement BIOS; the address of the error looked to be over the 1MB mark so it's probably a solvable issue with that expansion card. (The machine itself has only 512k on the motherboard.) The mismatched BIOS issue is mostly a cosmetic problem; if someone can be convinced to copy the ROMs from their unit then a few minutes with an EPROM programmer will fix that.

                              Here is a good reason why someone might have decided to update the original BIOS.

                                Definitely not worth that much to me...and pushing it to bid as much as I did, which I wouldn't have done for any other model computer. I also have my damaged 3000, figured if it was just the BIOS chips, I could try swapping them with the ones from my board. Though at this point, I'll just have to hope that just maybe I can repair the damage...a long overdue project.
