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.

    Anything special about the LCIII?

    They seem to be selling quite well were I am and I am baffled as to why?
    Was there something special about them?

    Maybe because it's the least crappy of the original LC series?


      I laughed for about five minutes after reading that response.


        Well, all in all it's a pretty nice machine.

        was not really fond of LC series, but have a few now, a better machine anyway than LC and LC II's.

        pretty useful for doing a lot of things (creating floppy discs...)

        the case being slim, also easy to stock everywhere.


          I remember I had stacks of them 10-15 years ago and couldn't give them away or even pay people to take them. They would ask if it had the Apple IIe card, and if not, no interest at all.

          I didn't think they would have any comeback in value. Lesson learned. However, they are a cheap machine and most don't work anymore anyway.


            The LC III and III+ are popular because they're not crippled like the first two LC machines were.

            Despite Apple retiring the 68020 CPU on the Macintosh II earlier in 1990, they re-introduced it on the Macintosh LC later in the year. But this time they crippled it with a 16 bit data bus (the 68020 is a 32 bit CPU.) They also artificially limited the machine to have a maximum of 10 MB of RAM (2 MB onboard, 8 MB in 2 x 4 MB 30 pin SIMMs.) You could install more, but the machine wouldn't recognize it. The LC had the weird resolution of 512x384, and required a now difficult to find 68 pin VRAM upgrade to use 640x480 video at 8 bit. There was also no 68881/68882 coprocessor socket, but you could add one with a PDS upgrade card. All of these issues make it a hard to use machine now because you're basically required to use a CRT for the weird video resolution, and many applications won't work below 640x480.

            The LC II was a slightly less crippled LC. It upgraded the CPU to a 68030 @ 16 MHz, but was still essentially the same besides the onboard memory being upgraded to 4 MB.

            The LC III fixed all of those issues. The 68030 was upgraded to 25/33 MHz on a full 32 bit bus with a socket for a co-processor. It had 512k of onboard VRAM so it could do 640x480 at 8 bit natively, or 16 bit with a 256k VRAM upgrade. It could also do 832x624 at 8 bit with the VRAM upgrade. You can overclock an LC III to LC III+ speeds (25-33 MHz) by moving some resistors on the motherboard. Just make sure the CPU has a heatsink and fan or the machine will be unstable.

            Yeah because the capacitors leak and fail. My LC III had this happen awhile back, it was a pretty irritating process to recap the board because of the SMD capacitors.


              My first freecycle conquest was a pair of LC III's ages ago (with school markings of course). Some guy had a mobile home full of them. One of them promptly whistled itself to death (bad caps) and was probably my fist recap job (worked fine after).

              The units themselves are the best LC model (not crippled) and Ethernet cards for them are pretty cheap. If you are on a budget and want a 68K mac then this is your best bet (have you seen the prices for full blown 68k machines lately?). I actually have a Daystar adapter for an LC III that will let you run a 68040 in it (have not bothered to try it yet). I also removed one of my LC III motherboards and put in a full blown 68040 board (heatsink barely clears the cover).

              I also have an LC I with dual floppy drives just because of the oddity of it.
              What I collect: 68K/Early PPC Mac, DOS/Win 3.1 era machines, Amiga/ST, C64/128
              Nubus/ISA/VLB/MCA/EISA cards of all types
              Boxed apps and games for the above systems
              Analog video capture cards/software and complete systems


                Because I had one new as a kid in 1993? Well, not me personally, but the family?
                It is a mistake to think you can solve any major problems just with potatoes.


                  I just realized why the ones I saw sold so fast, they had Apple IIe cards in them.


                    If they had the Y-cables as well, that would make a great little box.

                    My IIe card is in my Mystic Colour Classic, though.

                      The LC series carries an odd sort of nostalgia for me. The middle school I attended had three computer labs full of LC IIs, along with several others in the school library.One single LC II in the library had some sort of connection to the internet, and was my first introduction to the World Wide Web. A few of the other library LC IIs were connected to Pioneer CD-ROM changers loaded with various encyclopedia and other educational CDs.

                      The LC IIs in one of the computer labs were equipped with Apple IIe cards, which I can remember making use of all of one or two times. I remember being taught to use Open Apple+Y to eject floppy disks instead of using the Eject command in the Special menu, which I found a bit odd, but went along with. The LC IIs in one of the computer labs were equipped with Apple IIe cards, which I can remember making use of all of one or two times. The LC IIs in the main lab (possibly the other labs as well) were connected to an Apple LaserWriter printer via an AppleTalk network. Pretty high-tech stuff for the early '90s, and far more advanced than the Platinum Apple IIes I'd used in elementary school.

                      When I was in college, one of the buildings had a two-floppy drive LC show up in a trash pile along with an external hard drive and CD-ROM drive (caddy-type). I grabbed the HD and CD-ROM drive for my Mac SE, but didn't have enough room in my backpack for the LC itself, so I left it behind. I later regretted this decision, as an examination of the contents of said HD revealed that the LC had likely had an Apple IIe card installed in it. This touched off a search for one of said cards which took several years to resolve.

                      One of my friends had an LC III as their main computer, which I eventually ended up acquiring. It worked last time I tried it, though the external SCSI port might be a bit flaky. Once I finally managed to acquire a IIe Card along with the Y-cable (two separate purchases at the MIT swapmeet on the same day!), I installed it in the LC III, installed the software disk on the HD, and it's worked fine with everything I've tried with it thus far. Guessing it'll need to be recapped at some point, of course.
