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.

    Tandy 102 or little Christmas for me...

    I collect all type of portable devices, and Tandy 100/102 has been on my radar for some time. However, either the price was not right, or the unit was in worst condition than I expected. Finally I got a really good deal on Ebay, with Tandy 102 and accesories. Today, when I received the package (12 kg), I had a feeling like I was opening a treasure chest. When all, what was inside the package was on the table, I was pretty speechless - many accesories were not even mentioned in the listing:



    The package includes:

    Tandy 102 with little yellowing, but no visual damage, with Super Rom installed, and with original package !



    Original black carry case for Tandy

    Two ! Tandy external floppy drives, one new in package, never opened:



    Two 128 K external storage cards (new to Tandy, but does look so)

    Two 128 K ROM chips - do not know the contents

    Original Trs-80 tape recorder in working condition, only the cord is missing, but that should really be a minor issue:



    Software library in leather wrap, package with two cassetes, does not look used:



    Original Tandy floppy storage box with several floppies with basic programs (untested yet)

    Several original Tandy cassetes with original design:



    Many books and reference manuals, including software ROM manuals, technical reference, Basic reference and a large book: "The Tandy 200 portable computer", with all functionality described step by step with programming examples:



    Two cables, which I have not identified yet - maybe someone can help, in first picture, lower right.

    Since I am totally new to Tandy series, what are suggestions, where do I start? One of the first thing would probably get cable from recorder to Tandy, and to back up all useful data from the tapes. Probably serial cable for connection to PC, what else?

    What other accesories I might need or be missing? Thanks!

    Could you do a separate image of just the two blue cables including a close up of the connectors? I mean they look like standard floppy drive cables which would be strange to see with a Model 102.

    The main thing you are missing is the PDD drivers for a PC. Go to club100.org and get a set. Copy all the floppies directly to the PC.

    Two PDDs, you are so lucky. Enjoy.

      I believe those are printer cables, header connector on one end, Centronics parallel on the other.

          If you have an old stereo with a double cassette deck then you can copy the tapes onto ordinary audio tapes as a backup.

          Pretty cool package, seems it also came with Lucid, so you now have a spreadsheet program. ^^

            Just a little status update. First, thanks everyone for suggestions, will try to back up and check the software I have, when I will have a little bit more free time.

            As for connectors, close up photo is here:


            I do think it is probably Centronics connector, I just had no experience with that - when I started to use computers, LPT was most commonly used.

            Tried to play a bit with Tandy 102 - decided to install floppy drivers and format a floppy. Connected floppy drive to Tandy, inserted utility floppy, switched to Basic, typed command for floppy install, floppy drive made some sounds, and then stopped. Tried several times - the same. Took out second, never used floppy drive - everything worked as expected, format completed succesfully as well. As a person, who has no experience with Tandy before - everything is so simple, so easy to get used to the commands and interface - I like it!

            Then I returned to the floppy drive problem. Sure, I could just keep broken one for parts, and use new one, but I simply can not - I want to leave this "new one" in this condition for a long time. Carefully put it back in the box, and took a broken one - tried to format floppy - was getting "disk out" message, after a short motor sound. Tried floppy disc cleaner - did not work, and I finally noticed, that floppy disk is not turning at all. There had to be some mechanical problem.

            Took a set of screwdrivers, and opened floppy drive - everything was coming apart pretty easy, and soon I noticed the source of the problem:



            The drive belt was off. In fact, there was another problem as well - it was very loose, so then motor would not be able to spin the disc even with it in place. Looked around for replacements - found none. Finally made at least a temporary solution - the belt is running in two layers now, and the grip is strong again:



            Final test, after putting everything back:

            Format the floppy - OK
            Copy a text file to the floppy - OK



            Hearing the drive working properly again was a music to my ears. At least for now, I have two working floppy drives again...

              A 36 pin Centronics connector is typically used a the printer end of a parallel printer cable (like the cable you have). On a PC, there is a 25 pin DB-25 male connector on the other end, on the Tandy 100/102/200, it uses a header connector. The cable you have is definitely for a parallel printer.

                Thanks for the tip, the drivers do work fine on my Libretto 50ct, works great!

                However, I do not know how to use the expansion RAM card - installed new batteries, plugged in to Tandy 102 expansion port, and well - nothing happens. Do I need special drivers for it? Maybe a command line? I have found no info on these cards on the Web, unfortunately. Below is the picture with connectors on this card:



                Here is the photo of ROM slots with 128K memory ROM in place - it should show software to switch memory banks on menu, but there is nothing:

                  Problem solved! I did not know about command "CALL 63012", which loads data from ROM. Too much used to Plug and Play hardware I guess

                  However, working with data on this machine must have been a real problem, unless they were frequently transferred to the "Big" computer. For example, If I want to use Super ROM and memory expansion, it means frequent pulling out and replacing ROM modules , depending what I might need - storage or additional programs. I do not think ROM modules would last very long that way, from the other side I guess there were not many who bought this RAM expansion , which did cost about half of the the price paid for the Tandy.

                    Some programs can be copied from ROM to memory or the floppy drive. You may be able to copy them from ROM to floppy, then floppy to the memory expansion...
