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.

    Wizards Castle for the Exidy Sorcerer - Bad Dump?

    I was looking at Tezza's great Exidy Sorcerer software page the other day (https://www.classic-computers.org.nz...-sorcerers.htm) and I saw that he found a copy of Wizards Castle. However the wav file doesn't seem to work for me, it may have errors. Can anyone else test this and see if it works for them? Tezza's credits say that it came from Sean Corr, does anyone know him?

    Are you using Mame? Mame does not handle original 1200 baud files very well. I tried the 300 baud file and that works fine.

      Actually I'm using a custom SD card loader that a friend developed for my sorcerer. To use it you have to convert .wav files to .bin files using tapetool2. It worked for all the games I've thrown at it so far except for Wizards Castle and Lost Dutchmans Gold Mine. For both of these it gives me checksum errors. This is syntax I use to convert them:

      tapetool2.exe --sorcerer 'The-Wizards-Castle-(1980)(Joseph.R.Power)-BASIC-Sorcerer-1200baud.wav' parseAudio --baud:1200 blocksToMame 'B - Wizards Castle.bin'

      When I tried the 300 baud file with this is gave me an 'unexpected EOF' error.

        I have used Mame to load the 300 baud file and then saved it to 1200 baud. The resulting file is here. It now loads without errors in Mame so you may have more luck with it.

          That appears to work! Thank you. Do you have a corrected version of Lost Dutchmans Gold Mine?

            Using the same conversion procedure with Mame this version of the Lost Dutchmans Gold Mine should work.

            Edit: I just tried the 1200 baud versions on Tezza's site using the JSorcerer emulator. They load fine so the wavs are not corrupted, there appears to be an incompatibility in the conversion tool to bin.

              I have no idea why the tool threw checksum errors on those original wav files, but your 'fixed' files worked just fine.

                I'm having problems with several of the Basic games.

                Lost dutchmans Gold - OD error in 60
                Smunch - SN error in 50152
                Super star trek 2.1 - SN error in 50152
                Sorcerer invaders - SN error in 50152
                sSarbase hyperion - SN error in 49972
                Trots horse racing - SN error in 49940
                Word squares - SN error in 50152
                X-Nim - SN error in 50152
                Space - SN error in 50152

                Anyone have an idea?

                  Have you been able to successfully use tapetool2 to convert any Exidy Sorcerer BASIC programs from .wav into a .bin that you can load from your SD card thing?
                  I'm not sure I have used it for BASIC programs.
                  If it's a bug we can get it sorted out.
                  It's telling that you are getting syntax errors in the same (presumably non-existent) line numbers across different programs

                  P.S. Wizard's Castle wasn't a dump. Sean OCR'd the type-in listing from Joseph Power's original article [1,2] and even corrected some (original) bugs.

                    Funny, I have that same print out and I was going to type it in eventually but never got around to it. My friend said that it was written in the computer shop he used to work at so he wanted a copy to play with.

                    Yes most BASIC programs I have converted do work. I think the problem is the Tape Simulator I'm using to load games from the SD card to the Sorcerer. My friend said he may have coded to BASIC start vector wrong. He's looking into it.

                      Hi, I'm the Sean Corr guy referenced by the OP. I joined VCFED last year but had issues getting the account going. Anyway, I'm here now and look forward to contributing and learning!

                      As exidyboy said, the tape file was not a dump/analog copy but an OCR > heavy edit > load to Sorcerer > tape save. One of my interests is scanning old Sorcerer list printouts (Z80 or Basic) and using automated workflow, getting them running and saved in digital .wav format.

                      @tempest: glad you got it working in your setup. I also echo exidyboy's comments regarding the phantom code lines. I find that a bad Basic load will invariably LIST perfectly well at first, and then dribble down to meaningless lines. In fact, when in doubt, I sometimes do a LIST 30000 in Basic as the first step to see if there is any corruption. Not many Basic programs have lines beyond that region so it's a good initial test.
