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.

    OT or not so OT: do you use a calcutor w/regularity

    Forget about cell phones. Is there a calculator you have around that gets turned on at least say twice a week, which isn't often at all clearly. I pulled out my old HP 49g (x2) recently, even bought cheapo batteries as I didn't feel like searching for rechargeables. It's utterly unusable imho. Not interested, though I still love the appearance. About 3 weeks ago I ordered a 39g+ iirc from aliexperss, similar in appearance (both blue), and although it may not have all the utility of a 50g (sold mine years ago), it has a similar processor. I actually ordered another calculator, the 39GII iirc, but mysteriously the order got cancelled.

    It seems at this point calculators aren't going anywhere, despite people saying they don't use them anymore. The nice thing, at least over a cell phone app, is you get to press actual buttons. But even calculators come with touch screens these days (HP Prime, any TI have it yet?). I also have a Prime, but as I tend to be something of a brute it remains hidden and protected most of the time. Not something you necessarily want to use from day to day. But that's me.

    There are times that I would be lost without my trusty HP16C. I've gone through a grand total of 3 sets of batteries since I purchased it back in the 1980s. I have replaced the LCD display after it developed the "bleeding black" disease. Fortunately the HP15C used the same display and is very common.

    BTW, What's a "calcutor"?

      I find the Windows calculators quite adequate for my needs and they're always at hand at the push of a hot key; the unit conversions are a nice bonus.

      And then there's also Excel...


        I used the generic 4 banger calculator on my phone all the time.

        If I need something more substantial, I turn phone. I have a 48G simulator that I use.

        I find I can't use the regular 48/49/50g simply because there's no backlight, and I find the LCD hard to read. The form factor is nice, for sure, but the display is far below what the phone provides me.


          I'm fairly good at mental arithmetic, and my life circumstances and hobbies are such that A. I rarely find myself needing to do math that I can't readily do in my head, and B. when I do need to, it's usually for some specific project/application where it'd be more useful to write a quick script to do the work for me. But I still keep a modest little TI scientific something-or-other around just in case.

          Always thought it'd be fun to build a calculator for myself as a simple little project, but when I map it out in my head, it inevitably evolves from a calculator to a PDA to a laptop to the realization that it's not going to be simple or little after all.

            If I'm at home in front of my main PC, I will usually use a Casio fx-201P. Unless I need to copy/paste entered numbers or results, in which case I use Windows Calculator.

            Away from my main PC I use either Windows Calculator, or "Panacal" on my iPhone.


              I use one for quick and dirty calculation of disk% used on servers. What exactly I use depends on my mood. Sometimes it's just calc in windows, sometimes it's the scientific calculator I used at school and sometimes it's the red LED calculator my mum gave me years ago.


                Just wondering if anyone remembers the HP-16C. When working with 64 bits words and 48 bit addresses (bit granularity), it was a lifesaver.

                  Much sought after by CS students back in the day. I suppose for programming it had more utility then the 41 series.


                    Before that and the (really terrible) TI Programmer, there was the desktop SR-22. Far outside of my pocketbook resources; the department had one in the computer room. I remember it as being rather slow, even for a calculator.


                      I bought a HP 35s a few years ago to try out the RPN thing... I have it at work and use it multiple times a week typically.

                      At home I have a wide array of TI calculators. Normally go for the TI-35 or 36X. Trusty TI-83 for the history feature if I'm doing lots of calculations.
