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.

    C2n232

    Does anyone know where I can procure a ready made C2N232 gadget?

    It was designed by this gentleman:
    Marko Makela

    I am planning on pounding in a large basic program on my 8032 PET that is in a book plublished by Compute! but I have no way to save it as this point.

    Hi Dave,

    Does the 8032 support the Vic20 and C-64 cassette recorders? These are so common people can't even give them away. Or are you looking at transferring the program to a modern machine for storage?

      Tez,
      Yes, the 8032 supports a cassette drive and I have recently bought one that is slowly coming by U.S. Pony Express from New York. I suppose that would do for local storage, but I would like to have the software available to the PET users community. In its final form, it is a program that will be an assembly language RAM based version of Batpro that will safely reside in the upper 4K of RAM memory. It will work on all versions of the PET and the Commodore 64.

        A number of C2N232I exist in kit form, but it takes some SMD soldering skills to put one together. For various reasons those kits never were assembled, but if you want I can put you in touch with a gentleman who apparently have kits to sell.

        In the mean time, you could consider solder together either of the cbmlink compatible cables. They won't be as fast as the C2N232, but all are supported by the same software.

          Yes, please especially if the chip is pre-programmed. If not, is it a hard chip to program?

          This is a kind of confusing page with lots of cables. The PC that I will be using is an 133MHz Pentium with both a parallel and serial port. Is the cable I want to build the PC64 cable or the prlink cable with connections between the PET User Port and the PC parallel port?

          On the PC side, will the cbmlink software work with DOS or maybe an older version of Windows like Windows 95? I hope I will not have to compile a lot of C source code as that is a little over my head with my lack of software tools, etc. I took a unix class a hundred years ago and I don't remember any of it.

          The C2N232 software looks a little more straight forward for a non programmer.

          Thanks,
          Dave

            Yes, I think the PC64 cable is the recommended one if it works for your purpose. There should exist DOS/Windows executables, otherwise I may be able to compile some for you. I could even make Win32 command line executables using the MinGW/gcc compiler.

              Anders, OK I'll try to build the PC64 cable first. I will go over all the software information on the cbmlink page and if I get stuck, I call for help here.
              Thanks, Dave

                OK, I have the parts to build the PC64 cable. But before I get too far, can someone verify that on the PET side, I will be hooking up to the user port that contains the PA0 through PA8 signals?

                The cmblink documentation calls out the PB0 through PB8 signals on the cable wire list which I think must be a typo.
                Thanks, Dave

                  The signals have different names depending which C= computer you are looking at, i.e. compare the manuals for the VIC-20 and C64. Generally PA0-PA7 should be equal to PB0-PB7, but as you can see in two designs there is a PA2 which on the third (Amiga) design says CB2.

                    Anders,
                    I am well along with my pc64 cable as I started with a PC parallel port extension cable and cut off the socket end and will hook up the PET user port connector there. Oddly the wires did not follow the brown, red, orange, etc color code for 1,2,3 as I thought it might. I'm glad I buzzed it out.

                    Is it possible for you to build me a MS-DOS executable file with the following parameters:
                    Cable type: pc64
                    computer type: PET4001
                    Memory Expansion: plain
                    Thanks, Dave

                      I'll try to remember that for tonight, about 17-18 hours from now.

                        4001??? I thought it was for an 8032? In which case I wouldn't mind a copy...

                          Well, as far as I understand the serial software on the PC side should be identical no matter what machine you connect the cable to.

                            Well, I was actually just yanking Dave's chain, but if there really *is* a 4001 model then my face will be very red indeed...

                              It doesn't seem too uncommon that people refer to the 4000 series as the 4001 series, even if there is no machine with that specific number. Likewise for the 3001 series, which would be equivalent to the 3000 series. I suppose people do this because they think about the 2001 and assume all PET/CBM should have a model number ending on 1 or higher.

                              Actually it seems in Germany and perhaps Sweden, the PET/CBM 3008 was sold as 3001. I can't say I ever saw one myself, but I may have missed that detail. I suppose this was an alternative to calling it 2001N.

                              This page claims the PET 3001 had to be renamed as CBM 3008 due to the brand conflict with Philips.
