    Atari Pong PCB Reproduction

    For the last 6 months I've been researching and planning to make a reproduction of the original Atari Pong PCB and thought I'd share my progress.

    Original Atari/Syzygy Revision 'E' PCB


    I've repaired a few Pong clones and have become reasonably familiar with the schematic layout.
    There are a few newer versions of the schematic available on PDF but they are all on a 16 page layout.
    I wanted firstly to reproduce the original schematic on one sheet then produce a PCB layout from that.
    One of the biggest challenges is not having an original PCB in front of me to ensure the dimensions are correct and the layout is perfect.
    A KLOV member is measuring his PCB for me and I should have exact dimensions next week.
    I've found a great scan of an unpopulated PCB which prints close to the original size (I placed an IC over the holes and it matched almost perfectly) I've been working off that for the layout and confirming traces.





    I did a quick layout in Free PCB a few weeks ago but have since moved to Design Spark and will redo it later when I've completed the schematic layout.



    16 page Pong Schematic PDF...

    Original schematic broken down into sections...



    I've completed about 30% of the schematic so far.

    To make it easier to read, I printed the original schematic onto A1 paper at Officeworks.



    I've never used PCB design software before so the layout isn't perfect but as long as it works, that's good enough for me.
    I'll more than likely do two versions, the first will be a 1:1 reproduction and the second will fix the 6 bugs in the original design and possibly not include the AC rectification/regulation components or have a couple of jumpers to bypass it and run directly off +5vDC.

    The initial work on drawing up the schematic is done, There's still plenty of tweaks and adjustments left to do.

    Have you thought about implementing it in an FPGA?

    Love this project BTW.

    Yeah I've looked into that as well.
    There have been a few people who had a go but nothing I can find is the same as the original.

    Does anyone here use Design Spark PCB?
    If so I could do with some help locating a 7450 in the library. I've substituted a 74LS51 for the time being.

    I'm using FreePCB but wanted to try Design Spark. Hard for me as no NBN here and design spark requires online activation.

    I tend to create my own footprints. Not hard to do and ensures it's done properly.

    Use the component wizard to change a similar item to the one you want.

    Cheers mate, the 74LS51 is easy enough to modify.
    I'll have a go at it tonight.
    Is there an edge connector in the library anywhere?

    I hope this helps. I also hope they show in the right order.
