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.

Tandy 1000 Upgrades.

new posts

    I have a Tandy 1000 similar to yours (except with dual 360K Floppy Drives), and that I've added a SCSI Card and 500MB SCSI HDD out of a Power Macintosh 7500/80, and a 3COM EtherLink II TP network card so I can transfer files without disks.

    My hard drive is mounted internally, well, more like "wedged in" between the floppy cage and the PSU using a cardboard mount (which clears any vent holes so the PC can breathe properly) and wired in using a cable split between the top floppy and the hard drive. It's been running like this for 2 days straight now with no issues. The cable runs along the top of hte floppy cage to the controller card in the 3rd slot, which is a cheap Advanced Information Concepts SCSI Card which is both internal and external (it does look funny booting in the 40 column text mode at start though).

    I prepared the drive by installing the SCSI card into my 286 and installing the Operating System and Networking (with NetBEUI and IPX/SPX protocols) with Microosoft LAN Manager 3.0 from floppies on that machine. Then I installed the pre-setup hard disk and controller + card into the Tandy, configured the config.sys and autoexec.bat files to multi-boot to a clean boot, a standard startup, and the networking startup. I used the network startup to map to my file shares on my modern computer (Pentium-D) and pulled all the software over to the Tandy from there.

    A quick way I used to pull a huge amount of software over to the Tandy was I wrote batch files on the host machine that basically did all the DOS commands I needed to copy the files over. I'm not the best programmer in the world so it basically looked something like this...

    echo "DOS FIles For Tandy 1000"
    echo "Script for Quick Installation of DOS Programs"
    md c:\sierra
    echo "now installing Leisure Suit Larry in the Land of the Lounge Lizards"
    md c:\sierra\lsl
    copy *.* c:\sierra\lsl
    echo installation of Leisure Suit Larry Complete....(and repeat this code ad nausium)
    After pulling over my programs I had a pretty much was able to run whatever I wanted off the hard disk drive. Whenever I want to install some more software, I just reconnect to the network and either run a batch file, or in some cases install by hand. The only thing that does not work right most of the time is running real iinstall programs from the host machine, might just be because it's an 8088 and 8088's can't run multiple programs at once like may be required to do a "server" based install.

    I'll also put a plug for the XT-IDE card in here, I may eventually buy another as a backup for the Tandy 1000 in case I run out of SCSI Drives (as I don't have any left that work with that computer, the 1.2 GB is too slow and has write errors because it expects a MUCH faster interface, and about 8-9 IDE drives I can use without issue on the XT-IDE card). There is plenty of power in 65 watts for a hard disk and a network controller of more modern spec (it's not like I"m running a large (in size, not capacity) Stepper hard disk from the 80's but rather a 500 MB "energy star" compliant drive out of a md-90's apple).


      Has anyone tried the XT-IDE in a Tandy 1000 SX?


        I don't have a SCSI card, but I have a CD-ROM interface card, but I doubt it would be of any use.

        I have a 250 MB SCSI drive made by Apple, I guess I just need a SCSI card.

        I still don't know how to get files to the Tandy with the floppies.

          Nevermind, I need an 8-bit one. Anyone know a good, readily available 8-bit SCSI card?

            i have an XT-IDE in my Tandy 1000 TL class, i can't imagine the SX is much different, works fabulously now too
            Nothing beats the roar of a 36yr old drive coming to life after a decade in storagg


              This is what I get sometimes, it's either this or the "File not found" error. This is with a Cyber Pinball disk (yes, I know it wouldn't work, it is shown because it and Apogee disks were the only ones not to give me a "File not found" or "General error" error) :


                If you do a DIR on that diskette on another machine does it show normally ?
                If so then it could be a dirty head on the Tandy diskette drive.

                I recall seeing weird stuff like this when doing DIR on some copy-protected bootable
                game disks. Something about the diskette format that the DIR command couldn't


                  It reads it just fine on other computers. I'll get a drive head cleaner.

                  Hopefully that's all I need to do...


                    It is possible that your copy of Tandy MS-DOS may be corrupted, either due to data loss or due to a virus, thus causing the gibberish to be displayed on the directory listing. You can download disk images of a clean copy of Tandy DOS, although you'll probably have to swap the drives in the Tandy around so that the 3.5" drive is the A: drive, so you can try booting off it.


                    Regular Microsoft MS-DOS or IBM PC DOS will also work fine, if you happen to have an old boot disk from another computer on hand.


                      I was using IBM PC DOS, and I have a backup of it somewhere.

                      I still want to try cleaning the drive head first, especially since it loads 5.25 inch floppies just fine.


                        Have you tried formatting it on the Tandy first, then writing files to it from the newer machine, then taking it back to the Tandy? I had to do this to quite a few machines, especially Atari's ST; mine read any floppy disk that was started there, but not a floppy that was formatted on anything else.

                        /edit Do you have a copy of the DOS that came with it? I have PC-DOS for Tandy somewhere, I think I can copy it for you. I'll check tomorrow when I get to 'work.'
                        The ancients knew *more* than us...
               They're baaaack!

                        Come and see for all your gaming needs! We have Zero-ohm resistors!


                          I'll try that.

                          No, I don't have Tandy DOS. I've been using IBM PC DOS.

                          How do I format in DOS? The normal commands I usually use don't work.

                            In Tandy DOS, just use FORMAT A: or FORMAT B: as necessary. Add /S to format a boot disk. You do not need to manually specify a 360K or 720K format.

                            If it tries to format a 3.5" disk as 360K instead of the correct 720K, you need to add the DRIVPARM command to your CONFIG.SYS file. This requires DOS 3.2 or higher, but you should be using at least Tandy DOS 3.3 -- which is what Radio Shack recommended you to be using anyway if you install a hard drive. Add the command DRIVPARM=/D:0 to CONFIG.SYS if the 3.5" drive is A: or DRIVPARM=/D:1 if the 3.5" drive is the B: drive.


                              An answer to the question of wether or not the XT-IDE will work in a Tandy 1000 is most likely it will. I have one in my 1000 TX and works great. have it hooked up to a small laptop drive right now an no problems at all.


                                Still gives me a "General Failure Error" when I try to format. I guess I need to clean it.

                                Longshot, but if I were to make a DOS boot disk in Windows, would it read and boot a more recent DOS version?
