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.

    Toshiba T3100/20 Boot Issues

    I just got a T3100/20 on eBay as-is. So here's what happens when it boots:
    First, an all-red screen. Then it tests the memory.

    Then it beeps and shows this screen:

    The only thing to do is press F1. Then it restarts, spins up the HDD, tests the FDD, beeps, and then turns off both drive lights and rests at a blinking cursor, where it remains indefinitely:


    I have an SCSI card for it, if I put it in it does the same thing but says "SCSI" in the boot screen. Any ideas what I can do with it? Is not the T3100 supposed to have DOS in ROM, or at least some way to enter the BIOS settings, or some way to boot from floppy disk?
    Help is, as tends to be the case, appreciated. Thanks.

    #2
    Update: I got it to usually get to boot a floppy disk. So this leaves me with three questions:
    1) Why isn't there a setting to enter the CMOS settings anywhere, and is it a DOS program I can download and run such as was used in the Satellite 250CDS?
    2) It sometimes says "HARD DRIVE INITIALIZATION FAILURE" on booting, and I cannot access the HDD, though it spins up - what are the first step to determining what's up with the HDD?
    3)Is there anything I can do with a machine that only boots to FDD and seemingly doesn't support any graphics? So far I haven't found any software (like a game) that can run right on the T3100.
    Thanks,
    Caleb

      If you have not seen it already, there is a T3100 maintenance manual at [here].

      The T3100 will have an internal battery to maintain the setting of the 'CMOS' SETUP. If that battery is faulty (e.g. due to old age), it may be the cause of your computer's symptoms. The battery is referred to on page 5-16 of the aforementioned maintenance manual.

        Yes, I've read the manual, thanks for the link though.
        Replaced the battery, no change besides no CMOS errors. Main thing I'm wondering is, why does it never give me an option to access the CMOS settings?

          I thought that the "press [F1] key" displayed was an indication that the pressing of F1 would take you into SETUP, but page 8-8 of the manual that I pointed you to indicates that for the T3100/20, Toshiba have emulated the IBM AT by placing SETUP functionality into the DIAGNOSTICS program. In the program, SETUP is the last menu option.

          page 8-7 of the manual indicates that the DIAGNOSTICS program is named TESTCE.

          There is a TESTCE.EXE in the \DIAGS\LOW folder of the Toshiba ZIP file available for download from [here].

          Some things to try:
          * After you set up the drive in the CMOS SETUP, perform the hard drive test that is in the aforementioned DIAGNOSTICS program.
          * Open the T3100/20 and then re-seat the connectors associated with the drive and its controller.

          The T3100/20 flyer [here] indicates graphics capability.

            As far as i can remember you had to hold ESC when powering up and then you got to the BIOS. Can also try F1 or F2 if that doesn't work. There i would check especially the HDD settings. WHen the system hangs on boot it is likely that the faulty CMOS battery resetted everything to default and that your HDD does not match the default setting, i.e. having the wrong number of Cylinders or so configured. Then you get the endless hanging. For real troubleshooting set it to "no HDD" then reboot and see if it still hangs. Try booting from floppy to check if that drive is OK.

            The T3100 has CGA graphics and so you can run Windows 3.0 (Windows 3.1 if you pre-configure it with CGA drivers), you can run old games like "Space Quest IV", "Monkey Island (CGA/EGA version ONLY), "Nuclear War", "Sim City", "Lemmings" and such... If you install a network card and WIndows 3.1 and Trumpet you can even use it for Internet browsing (Though most sites will cough up on old browsers).

              Yeah, it turns out on some models pressing F1 does subsequently bring up the settings menu, but at least on my T3100/20, the settings is a DOS program - thanks for the testce.exe, modem7, it worked great!
              I did the things you guys suggested for testing the HDD, and succeeded in getting it to respond, got it's info, and booted DOS from a DOS 3.3 disk made on my awesome flawless T1200.

              Thanks for the info kyodai! I've tried an assortment of holding down or pressing ESC, F1, or F2, but to no avail - so far the testce.exe is the only way I've found to access the settings. I did succeed in getting it to boot from FDD, so it's not the fault of the system board anyway. I'll replace the CMOS battery in a few days, that will tell more.
              Thanks for the suggestions, I will look into them! Sometime I'd like more info on running 3.1 on it too, that sounds quite interesting.

              I've made a lot of progress through chatting on the IRC channel, #vc on concrete.slashnet.org, thanks all you people on there! I'll have more info once I get the CMOS battery replaced.

                Ohhhhhhkay so now I have a different problem with booting. The display stopped showing anything ever (I have no external display of any sort). I tested the leads according to the manual, revealing that the power and mobo should be fine, leaving the issue with either the display or the display's PCB. I... don't know what to do about this, I can't really test the screen further than that nor buy a new one, and I have no idea why it stopped working or if it'll start working again. Sheesh, such is life I guess, perhaps it'll randomly start working.

                  Hi,

                  Did it stop working AFTER you took it apart to replace the CMOS battery?

                  If so, I'd go back over EVERY step of the dis-assembly/reassembly and check ALL connections.

                  Then report back, and we can try other things if need be.

                    One day, I brought my Toshiba 430CDT laptop out of storage, plugged it into mains power (house power), and then after I turned it on, I discovered a 'no display' symptom.
                    All of the expected booting sounds were heard.
                    Eventually, I discovered that if powered up the laptop with the main battery removed, the display appeared.

                    This turned out to be be a known isssue in the Toshiba 400 series ([reference]).

                    I wonder if the T3100 has the same issue.

                      Alright, I'm back! I'm very very sorry for the delay in responding, I was lazy, no excuses.

                      So I tried your suggestions, the last two posts, but no dice. I went ahead and bought a new unit so I'd have another PDP (plasma display panel) to test it with, and I'm very glad I did because I discovered many interesting differences between the T3100 and the T3100/20.

                      The T3100/20 has an AMD chip inside, maybe it's the BIOS chip I really don't know, while in the same spot the T3100 has a Toshiba chip. They certainly have different BIOSes: I have verified that the T3100 does let you change the settings by pressing F1 on boot-up, whereas the T3100/20 does *not*. You need a bootable floppy with testce on it for the T3100/20.

                      I made a full forum post about it on Bosaiknet: [Documentation] Full documentation of the Toshiba T3100 with lots of pictures.

                      So the bottom line is, the PDP no longer works; I verified that by carefully testing it with the one, then the other. That is most unfortunate but there's no help for it. I'll keep the T3100 that I used to diagnose it though, which works excellently! I'm selling the partially-functioning T3100/20 on eBay: http://www.ebay.com/itm/111890686511

                        Ah, I have just dug my 3100E/20 out to see if it works, see other thread.

                        I needed a new battery, putting that in and came up with BIOS screen where I could set the disc type. But after that it doesn't do anything but can't hear the disc spin up. At the moment it is all in pieces trying to get to the disc, what a rubbish piece of design. Have to have the screen hanging off the base unit by a flimsy cable. The cable seems to be soldered to the main board and connectors on the VFD are buried in the screen surround.

                          Interesting, I had thought the 3100E was a better model since it used an IDE HDD instead of MFM. I would guess that there should be some way to unplug the cable from the screen but of course I don't know - as far as there's any similarity between the T3100 and the T3100E feel free to check out my collection of images detailing each step of disassembly, but if they're too different that won't help.
