  1. I only got my first NTSC console about a month ago (my other consoles have been PAL) and I was surprised to see the extent of the rainbow effect on a TV set. Vertical single pixel lines that are supposed to be white are red, blue, green but never white. Never thought of this before while developing any of my stuff.

     

    In this memo from 1982 Karl Guttag is talking about a rainbowless version of the 9918 that they were testing.

     

     

    Well NTSC does stand for Never The Same Color

  2. If you have JAVA installed, you can just run the JAR file from the USB stick without having to install it. I think the JAVA install is the part your IT department would have a problem with.

    I've seen this movie a bunch of times, I can't seem to remember ever seeing a TI 99 in it.

     

     

    EDIT: just did quick run through of the movie, these are literally the only 2 scenes with computers in the whole film.

    Pretty sure that's a CoCo


  4. Ksarul to the rescue! :thumbsup:

     

    As he pointed out, I goofed up when I copied the bank switch circuitry from the multi-cart in that I connected the capacitor to the wrong end of the resistor. :dunce:

    When I rewire the capacitor correctly, the disk test works just fine on my "bad" system, and response time seems improved overall.

     

    And even better, it requires only a small modification to existing boards:

    Just wanted to get this out. I'll add a more detailed description about the fix soon.

     

    Thanks again, Ksarul, for saving my ass! :grin:

     

     

     

    I haven't soldered anything since my junior high electronics class, this should be fun.

    Instead of making one I decided to just buy one. Here is the one I bought a month or so ago. They make them as you order them. I got mine within 5 business days.

    I have one of these, It's nice to be able to tuck the speech module and the flex cable behind the PEB
