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.

    Sharp PC-1600 and accessories

    I have possession of a friends Sharp PC-1600 (not working, worn buttons) with a ce-1600p (cassette interface), ce-1600f (disk drive), (the three latter parts should work) power cord, and partial role of paper, and carrying case.

    Does anybody have ideas about how much would be a good guess as to how much these items might be worth?

    Thanks for any input

    Nice machine. The price is quoted as $10-100 here, but presumably that's for a working one. Is it hard to fix the buttons?
    WANTED: Cardinal 2450MNP modem.


      Thanks for the link. I haven't researched how hard it would be to fix the buttons or the machine itself yet. My friend was actually using it until recently when it quit working.


        Sharp Pc-1600 is usually a lot more expensive than the sharp pc-1500.I have seen prices up to 200-300$ for good working machines..



          You probally won't believe this, but I was planning to place a Want-To-Buy for a Ce-1600p printer. I have a 1600p, but have never been able to get it to actually print - it does everthing but press the pens to the paper. So I have been looking for one that either works or might be used to repair mine. The PC-1600 is a fantastic handheld - and has a dual processor in it. Both the processor for the PC-1500 and a Z80. My first computer was a z80, so I do some z80 assembler programming for my 1600. While the floppy drive is a fairly rare item, getting disks for it is even rarer. A couple of years ago, I aquired two new boxes of disks, but never aquired a drive for it.

          If you wish to contact me, I'd like to aquire the lot. I'd be willing to offer what I hope would be a fair price. You can email me through the forum here.

          I've been hoping to port the Byte Tiny Pascal to the PC-1600 - just need to get some time to re-write the run-time code. It would be great to actually write Tiny Pascal cone on it, and then compile it to Z-80 code.

          As to values:

          Last year I bought a new-in-box PC-1600 from Uderwood Distributers for $200. I just checked their site and they no longer offer them, so I guess they finally sold all their stock. On ebay, working units typically go for $100-$200, depending on condition.

          Last year, I paid $50 for my non-working CE-1600p printer.

          Haven't seen the floppy drive for sale.

          As to trying to repair the PC-1600, I have a couple that are not working, and, I've taken them apart, but haven't been able to fix either one as of yet. They do come apart fairly easy. I could send some phots of one opened up. Not sure how easy it would be to gt to keys though. I had hoped to get one of the broken ones working and then hard wire a RS-232 cable to it. But no luck so far.
