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.

    Awesome! I’m not really sure about networking, I’ve never done it.

    The Palm always had a nice form factor. I know my friend was disappointed when they got out of phone business.
    Thanks!

    Yeah, Palms we’re fantastic. Their software was (still is) excellent. Really a shame they weren’t able to stick around. The Graffiti handwriting recognition system is really nice as well once you get the hang of it. Funny how Xerox tried to sue them and claim it was “stolen” from their “Unistroke” system (which really looks quite terrible in comparison to Graffiti) and it turns out it wasn’t even Xerox’s idea originally, and their Unistroke patent was invalidated. I think Xerox was butt-hurt because Palm made a handwriting recognition system that actually worked and was easy to understand.

    Palm III 8MB upgrade success!

    I really cannot believe I managed to pull this off!

    One Palm I am very fond of is the original Palm III running the stock Palm OS 3.0. The Palm III comes standard with 2MB of storage, and over the past few days I have been thinking about this 8MB upgrade "hack." I remember reading about this a years ago and thinking there's no way I could ever do it, but I've gotten a lot better at soldering since then. There were aftermarket 8MB memory cards made for the Palm III, but it doesn't seem many people bought them, so they are super rare nowadays.

    This upgrade is for the newer revision Palm III that uses DRAM, versus the older one that used SRAM, which can only be upgraded to 4MB and is more difficult to upgrade.

    You can read all of the details about this upgrade here:

    http://www.interlog.com/~tcharron/Palm8M/III8M.html


    Here's a pic of the Palm III memory module when I first got the old chip off and was about to install the new 8MB chip:

    IMG_6354.jpg


    I saw several people that stated they removed the chip with solder braid, and was very doubtful I was going to be able to get it off that way, but after applying some flux and making a few passes over each row of pins with the braid, the chip popped right off! No pads were damaged or lost.


    Here it is after all work was done:


    IMG_6355.jpg

    IMG_6356.jpg


    I also cut away a portion of the little pad that keeps pressure on the board in the back case, as it was partially over the area where the wires now are, and I didn't really want it pressing in them. I also applied a drop of glue in the middle of each wire (after the pic was taken) to keep them secure.

    IMG_6358.jpg


    And finally, here is the palm reassembled and working showing 8MB of available space!

    IMG_6359.jpg


    I could not be happier! This really was a fun project (took me around 3 hours). I could have lived with the 2MB (as I had done for a few years already) because it is just enough for most of my favorite apps, but I wanted some extra space so I could play with some new software on here. One way I thought of getting more storage on here was to install a motherboard from a IIIx or IIIxe into it, but I wanted to retain Palm OS 3.0, which only the original III has, so this was the best option for me.
