    Yeah thanks dezbaz, dunno WTF I was thinking last night, I know mine is Atari and not LAI.
    Winter is here and I'm still riding more than gaming, my current goal = 100,000 meters elevation gain for the year - well ahead so far

    Still going on these

    Starting to add the top layer silk screen, and have decided to add the values of the resistors.

    The 14" screens had some different values, so I will think of a way to allow for that (Maybe add a key/legend on the board, you can refer to when assembling)



    I won't be doing a prototype, just a main run, as the tooling cost is high. Might do a run of 10 to 15 of them only, I think

    Yep, I will still use your creation mate

    I am working on a proto that uses the HV from an amplifone Colour, and the deflection from the LAI board, so yours is the contender for the job

    So you could feasibly use a regular colour TV Tube in a BW vector game

    More IDs done now

    Notes done as mentioned earlier

    Different type of triangulation used on a few transistors so they are soldered in more stable

    Looking good - it is all VERY time consuming AND nail biting (as you wait for the first boards) but I don't need to tell you that.….

    There are a lot of components on this sucker. I have removed about 12 components not needed on the 14" or 20" and added a few aftermarket pots too. They could be preset X & Y size pots

    We will see
