    Turns out the source code contains some unused prototypes for the iconic 'claw'!

      A couple looked like the Batman logo. That would have been cool.

    I'm really curious about the tech in this game, and this is for sure an adventure in architecture like no other - so I'll enjoy doing those notebooks and getting as far as I can to my own builds running, next time I'm in the 'lab kind of mood.

    What's really fascinating, is all the modding that has already started on this. Those of us who have really, really fond memories of Tempest, Back In The Day™, are sort of getting our minds blown, that the source is not only available, the PDP11 is there for the taking, and MAME can give you that ol' happy feeling, but also there are new versions not just to be played, but to be made .. SVG to playable tunnel, wtf?! Delightful!

    Kinda neat, imho. I think this aspect of the retro- scene is one of the reasons its so compelling - and important - as it quite clearly demonstrates that technology doesn't get old - its users do. There is always a new way to apply technology, even if it was created 'ages' ago ..

      You should see the first principle reverse engineering Dave Pl did on YouTube.

    This has to be one of my favourite games of not my favourite game.

      Mine too.

      TEMPEST

      ROBOTRON

      DEFENDER

      ASTEROIDS

      KABOOM!

      All these games have simple dynamics that play out in interesting ways. KABOOM! is on the list for one reason in common with all these games, and that is the game ramps up to real human limits.

      Flat out, not everyone can play these games to their potential.

      The other common attribute all these have in common is they all can trigger what I call, "the trance" and I have heard others call, "The Zone." Basically, the world kind of fades away, leaving the game and you in a state where thought is action!

      And that state is very highly addictive.

      It also changes a person in subtle ways. When we reach that state, we become aware of our minds in a way not too many experiences can bring on.

      Those simple dynamics in combination is where the magic lives! Each enemy has agency of sorts, and behaves in specific ways too.

      All of that makes the game playable. If it were more random, it would just be frustrating. Some things are random, spawn points and such, but the rest is governed by rules intended to just punish the player while taking them to human limits!

      Awesome gaming if you ask me.

        Kaboom for Atari was amazingly mindless and addictive.

        Defender/stargate. I think I actually played the sequel more.

        Galaga

        Outrun

        Xevious

        Star Wars/ESB

          Nice selections both of you. Mines would be in no specific order: Battlezone. Asteroids. Pacman. Tempest. Pole Position.

          BTW, even if those are my favorites I'm really bad playing them.

          • ddingus 200 days ago
            Your addition of Battlezone made me remember the Cinematronics games!

            Star Castle, Armor Attack, Tail Gunner (I think), and both vector goodness and real sound, full with bass notes front and center.

            • bmonkey325 199 days ago
              Yes! All correct. Don’t forget Rip Off. The ultimate two player coop
              • ddingus 197 days ago
                YES! 8 had forgotten that one. Good grief it was a lot of fun.
          • bmonkey325 203 days ago
            Nice. I spent lots of money on all of these games

            Bad. Lol. I think I got to red levels on Tempest once. Maybe twice. I still play play because it’s fun. My top score on asteroids is in the 70,000. And I’m sure I never completed any run on outrun despite owning the actual standup for a couple of years.

              "Because it's fun"

              Damn right.

        • ddingus 200 days ago
          Right on!

          There is something like magic at work with Kaboom! It is one example I show people what racing the beam means. The game is simple and the graphics are crisp. All good, buy then we get to motion...

          That is compelling and fast! Too fast for some people.

    Also. Dave Plumber (davepl) who holds the world record score for tempest did a series on hacking Tempest :
