Forum 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.


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.


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.



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.


"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.

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.

    Downgraded Ultima II (From Re-released version 1985 to Original release 1984)

    I've got original disk of Ultima II ago.
    It consists 3ea disks.
    Disk 1 <-- 360KB (Re-released in 1985 with Sierra's Copy Protection just like King's Quest II/III/Black Cauldren)
    Disk 2 <-- 160KB (Same as original released in 1983)
    Disk 3 <-- 160KB (Same as original released in 1983)

    But I wanted to be downgraded disk 1 of ultima II with original release in 1983.
    Original release version of disk 1 is 160KB. (Copy protected sector is located on 20/0/5, but it can't read with normal method but it needs read track command of fdc.)
    Due to any users help, I can get Kyroflux (KF) image of disk 1.
    The problem is that I don't have Kyroflux but Trans Copy Board (TC)

    TC can't handle KF image.
    I couldn't downgrade disk 1 correctly because of writing copy protected track (20/0/5)
    But, thanks to PCE's tools (pflux.exe and pri.exe), KF image can be converted to TC image.
    If I have KF device, I could write to disk on windows easily.

    Anyway, KF image can be converted to PCE emulator's image (.pri .psi) or Trans Copy image (.tc).
    My Ultima II is now changed as original release.

    Whoa, this is huge! Where can I find copies of these tools? I want to test reading an image with KF and then writing it with an option board.

      http://www.hampa.ch/pub/pce/pre/pce-...flux-win32.zip

      You can see the pflux.exe , pri.exe and psi.exe in bin folder.

      How to convert?

      As you know Kyroflux images exsit as total 168 files (track.00.0.raw ~ track.83.1.raw)

      run pflux as follows

      pflux track00.0.raw -p double-step -h 1 -p delete -r 600000 -p decode pri disk1.pri

      Then you can convert .pri to .tc (Trans Copy image) by using pri.exe

      pri disk1.pri disk1.tc

      To run PCE emulator

      you can convert .tc to .psi by using

      psi disk1.tc disk1.psi

      (.pri <-- pce raw image / .psi <-- pce sector image)

      According to author of PCE (hampa), .pri image is nearly similar to .tc format. (But not same)

      But to convert MFM track (0-39) , FM track (40- ) and sector which can be accessed by Read/Write Track Command method, you need to run as following.
      (This must be more difficult)

      # Decode at 600 KBit/s (for MFM)

      pflux track00.0.raw -p double-step -h 1 -p delete -r 600000 -p decode pri disk1-mfm.pri

      # and extract tracks 0-39

      pri disk1-mfm.pri -c 40-99 -p delete disk1-mfm.pri

      # Decode at 300 KBit/s (for FM)

      pflux track00.0.raw -p double-step -h 1 -p delete -r 300000 -p decode pri disk1-fm.pri

      # and extract track 40

      pri disk1-fm.pri -c 0-39 -p delete -c 41-99 -p delete disk1-fm.pri

      # Merge the two images

      pri disk1-mfm.pri -m disk1-fm.pri disk1.pri

      # Convert .pri to .tc

      pri disk1.pri disk1.tc


      But I don't know KF image with weak bit track (Mainly on Track 0) can be converted to TC image correctly.

      I've tested the following.

      Ultima II <-- Original Release (1983) with KF (Copy protected track : 6/0/1) (Only 256 bytes shown on Anadisk : CRC-DATA / MFM-Half Size)
      Ultima III <-- Original Release (1984) with KF (Copy protected track : 20/0/5) (Not shown on Anadisk : CRC-ID / MFM-Half Size)

      Except Track Length, Written process has no problem by using converted TC image.


      # Decode at 600 KBit/s (for MFM)
      $ pflux disk1.pflx -p double-step -h 1 -p delete -r 600000 -p decode pri disk1-mfm.pri
      # and extract tracks 0-39
      $ pri disk1-mfm.pri -c 40-99 -p delete disk1-mfm.pri

      # Decode at 300 KBit/s (for FM)
      $ pflux disk1.pflx -p double-step -h 1 -p delete -r 300000 -p decode pri disk1-fm.pri
      # and extract track 40
      $ pri disk1-fm.pri -c 0-39 -p delete -c 41-99 -p delete disk1-fm.pri

      # Merge the two images
      $ pri disk1-mfm.pri -m disk1-fm.pri disk1.pri


      This protection type (Only accessed via Read/Write Track Command from FDC) is used as the following games I've checked.

      Gato (version 1.2 - 1.3)
      Hardball I (Disk 2 -- EGA)
      King's Quest (Booter version for PC/1984)
      Pinball Wizard
      Sierra Boxing (Booter version)
      Tau Ceti
      Top Gun
      Ultima II (1983)
      Ultima III (1984/1985)
      Troll's Tale (<-- I don't have it. wanted!)
      Wizball (Thunder Mountain)

        Thanks very much, I will test this out when I get my kryoflux up and running.

          I've tried to convert teledisk image to .tc image by using pri.
          According to author, overlaped track/sector can't be converted and fm Track/sector also too.

          If Teledisk / CP2 / PSI image can be converted to .TC image, this will be very interesting.

          But I don't know KF supports weak bit track/sector just list TC.

            If I understand correctly, you could be able to dump a disk with Kyroflux to raw tracks, use the pflux.exe utility to convert them into a .pri image and then use the pri.exe utility to turn the image into a .tc image which you could write back to disk with an Option Board. Interesting but cumbersome, especially as you would need one very expensive piece of disk imaging hardware and another very rare piece of disk imaging hardware.

              Yes, it is very hard and expensive to get TC Option Board than Kyroflux.
              If TC image is converted to kyfoplux image, it will be very excellent work.
              It is also interesting work for user who don't have both H/W. to run on emulator.

                The reason I'm interested is because the kryoflux allows anyone to dump "perfect" images (supposedly, I have yet to test mine), but the kryoflux cannot write images back to disk. If a kryoflux image can be transformed and written back with an option board, that solves a major problem.

                  If there is software to convert the file to the TC format, wouldn't it be easier to convert it to the ipf format Kyroflux uses and use the Kyroflux to write back to the disk. If Hampa did that, there would be many more converts to the Kryo.

                    Oh, really?

                    I didn't know Kyroflux can't handle write copy protected image to original disk.

                    I've tested Ultima II / III to convert.
                    I'll test King's Quest II soon.

                    By the way, do you have Sid Meier's Pirates! (432.01) (PC) and Solo Flight / Spitfire Ace original disk?
                    I want to recover cracked image to original by using TC.

                      According to hampa, a few of .psi (or .td0 .imd) can be converted to .tc image too not only from kyroflux.

                      But there is limitation.

                      >(they are already encoded as either MFM or FM, PRI knows

                      I'll test more kryoplux image (Especially Sierra's copy protection)

                        To my knowledge, the kyroflux cannot write all types of images back to diskette.

                        I no longer own Pirates! or Solo Flight or Spitfire Ace so I can't dump them for you.

                              Ok.

                              By the way, do you have "Hard Hat Mach" original?
                              I've tried to edit "Hard Hat Mach" by using .td0 .cp2.
                              But it doesn't work.
                              I want to test it by your .TC image.
