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.

    I have descended to trashpicking

    We went to the e-recycler to drop off a photocopier today and discovered this arcade machine sitting in the bin. My wife mentioned how my daughter was looking to make her room 80s arcade-themed and opened the door to my grabbing it, which I did with great haste, since we also had a Home Depot rental van instead of our little Toyotas and could actually take it.

    https://drive.google.com/folderview?...h7XrSqm_lDpZx4

    Overall apart from being dirty it doesn't look too bad. I'm hoping my 'skills' at fixing vintage computer gear will be applicable here.

    Can't find much info on the company. There is a metal plate above the PCBs that says Scramble.. seems like a cool game if that's what it is. I figure if the tube is good that alone with the cabinet probably make for a decent freebie.

    Hard to tell with all of the dirt, but it looks like it has a JAMMA harness, so the cabinet could be adapted to play other arcade boards. Or you could get a JAMMA to PC board and shove a small PC in there to emulate basically anything. The limited button set would be an issue though unless you modified it to add more input buttons.

    With the inspection date of May 27th 1982 in the cabinet, this is probably the game you have:

    Jesus christ are the sounds of the game annoying. It looks fun, but I'd definitely turn the sound off.

    Before powering it up, I'd definitely completely recap the CRT's analog board, it looks like at least one of them has leaked, and the rest are probably not in great condition. Being almost 40 years old next to a hot vacuum tube all of their lives with no ventilation.

    I would be VERY surprised if the CRT didn't have any burn-in on it. Almost all arcade games never had a screensaver and various elements would be burned in, like the score counter and "insert coin".

      Good find! I've gutted a few of those over the years to convert to MAME boxes. A flat panel LCD screen, a Pentium II or III running a DOS MAME font-end, and a few quarters.

      Of course, the ones I gutted were far beyond repair. If you plan to fix this and get it running make sure to post videos when complete. Scramble was an awesome game that I plunked plenty of quarters into at the local arcade when I was a kid. I wish arcades were still a thing.

      Here's a Scramble bezel sticker that might fit: https://www.ebay.com/itm/164381565954

        Oh , and marquee: https://www.ebay.com/itm/173918583496

        Sorry this is not in the post above, I don't dare edit for third time. Might get marked as a spammer.

          So lucky to get that. I really hope you can clean it up and get it going.

          I see roms in one of the photos. Can you dump them? I might be able to find a match in MAME which will give you the maker's name and other details.

            Nice, I would have grabbed it as well if I was in your shoes. I always wanted to restore an arcade cabinet (doubt Id keep it because of the room).

              Hmm. I don't remember Scramble at all.. I went to a fair number of arcades back in the day. But probably I just missed it because I was so obsessed with any sort of driving games or Pacman related stuff. I can't wait to try it out, if that's what it is. It looks like a lot of fun.

              I feel like this cabinet must be JAMMA.. I would bet Coastal Games was a licenced vendor that basically offered these units to non arcade venues like restaurants etc.. I seem to remember some waiting areas having machines like these beside the cigarette machines (remember those? Lol). Probably they had some kind of service arrangement to change the games up every now and then.

              I really hope the monitor is still good. Although to recap the board will require me getting over my intense fear of CRTs.. 8bitguy and Adrian make working on them look so safe and easy...

                There is nothing wrong with trash picking, until the guy watching you through the window picks up the phone.

                  This is waaaaay too early for Jamma. But it's very easy to figure out the pinouts on the connectors since the game is still connected to the harness.
                  You can find help getting this up and running at

                  Easiest way to ID that board is to grab one of the eproms off of it, read it in and run a romident on it.

                  Good luck. I've been collecting and repairing arcade games for 25 years or so. It's a bad knock off, but might restore into something nice.

                    It looks like a Japanese made Tehkan "Lava" cabinet (also existed in Namco flavors) but seemingly OEMed for Coastal Games, Ltd. Pretty cool!

                      Inspection sticker says 1982. I wonder what Game(s) it plays.

                        I've ordered replacement caps for the monitor board.. however in the interim I was thinking about firing this thing up just to check out the power supplies for the PCBs. I don't see any obviously leaking caps on the monitor board but there is this cylinder thing that kind of reminds me of a penny roll.. it looks a little rough.. anyone know what this is (near bottom right):

                        https://drive.google.com/file/d/1T-P...w?usp=drivesdk

                        Am I risking fire etc trying to power it up as is?

                          The thing with 3PO on the top? I'd say it's a coil with a 3P capacitor attached. You could use a brush and gently clean all of that dust out of there - that would reduce the fire risk.

                            I'd just pull the board out and hose it off and let it dry in the sun.

                              So I cleaned up the board and then fired up without the arcade PCBs connected to test power from the PSU - all came up good, getting good +12v, +5 and -5V. So I connected the PCBs and fired up. The game itself (Scramble) seems to be working just fine as you can see in this video. It looks like the monitor is suffering from some kind of partial collapse. Maybe caps?
