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.

The rightmost keys are somewhat depressed - I think the plastic case may be impeding them. And the RESET key doesn’t budge at all. Can’t push it down any further as it’s already seemingly fully depressed. This may be related to the keys having been compressed by the coiled cable while the keyboard was locked into the face of the machine for 35 years. I want to take the keyboard apart but it looks to be press fit and I’m concerned about breaking the plastic trying to separate the keyboard halves. The connector is a DIN-5. Not sure what the wiring is on it… Any suggestions welcome!
    My IIe had a similar keyboard issue, it had somehow shifted to the side and the keys were hitting the housing, even the same stuck reset key. Easy to loosen and recenter on the IIe. Maybe a short drop on the left side of the keyboard?

      I was wondering about that -- seems like a good thing to investigate -- thanks for the suggestion. Now if I can just separate the keyboard halves safely...

        I tried some banging on it today but unable to shift the keyboard over. The two keyboard halves don’t quite fit properly into each other - sizing seems to be slightly off.

        Any recommendations for separating the plastic halves? I need something like a plastic flat screwdriver. I can see where the 4 spots are where the plastic tabs likely are that keep the board together.

            Thats great! I am trully envious on your CX pickup. I first read about the CX in Steven Weyhrich's book https://www.amazon.com/Sophisticatio.../dp/0986832278
            A great read by the way. It even pointed out as you stated how it was still in R&D when the company folded. Amazing its really the only apple II portable with a built in screen.

                It’s an interesting machine, more in the realm of a CP/M luggable like Osborne or Kaypro. There’s a Franklin 80 (Applicard) in the machine so I guess it is a CP/M machine. The monitor has thick glass and is super sharp. I was impressed with how clear the image is. Wish there was more of them around. I think there must be a collector or two with them, the others are in museum collections from what it sounds like from Bob.

                  There were a limited number of fully assembled units around the time things were starting to go bad for Franklin, two of them were in Franklin's collection of products and those were the two I had possession of. I kept in touch with most of the original core of engineers and none of them had one, but Franklin had a yard sale (I kid you not) and someone bought most of the pieces of CXs that were in boxes, then built whole units and sold them on eBay. So there are an unknown quantity of them floating around on the used market, but not many. I'd best almost all of them were assembled from bits and pieces, not whole units. I can't remember more than one or two sitting in Engineering during development but my focus was the Red Lightning and had nothing to do with the CX.

                  It should be able to boot CP/M. About 8 years ago I had a CX on display at VCF East running CP/M. Nothing special about it; any CP/M boot disk for the Applicard should work.

                    The guy I bought the CX from, he said he bought about 100 computers worth of pieces from Franklin and then assembled and sold them off (not CX’s specifically probably ACE 1000’s or other machines)

                    I’ll have to try tracking down a Franklin or Applicard CP/M disk. That would be great to try. If anyone has the means to make one, and send me a copy, please let me know.

                      I think the rarer card is the Color video card. I know the last repair I did on the 1200 The customer wanted me to find him a color card.. I came up dry even after 9 months of searching.

                      Ill tell you though. I would love a CX just for the portable aspect and I love luggables (with CRT's.. I try and avoid old LCD screens.)

                        At one point there was real Apple color generation circuitry on the 100s and 1000s, and dealers would unofficially install the few parts for customers. Definitely violated a very vague Apple patent. One hardware engineer at Franklin (Mike Wajda) spent a few months coming up with a fully compatible but non-infringing board design. It was ugly; at least one chip pulled from the motherboard, then a very odd shaped board installed, and quite few jumpers back to the mobo.

                        I do not know if the original color logic was on later motherboards, but it was all right around the back corner by the video connector.

                        Goofy story. While Mike was working on the color board, contractors were in the building running wires for something. Mike was staring at his prototype board when a ceiling tile suddenly fell onto his work. Broken tile, lots of dust, and a contractor poking his head out of the ceiling apologizing. Mike put on his jacket and calmly left for the day. He spent most of the next day cleaning up the mess and getting his prototype working again.
