The thing is, this specific TI99 I'm working on, exhibits the same type of errors as the video does thus far. I'm only using a multimeter, I don't have an oscilloscope. I'm worried If I skip to his 4th video, I might miss out on something important, but don't want to follow the video for hours If he is just testing useless things. From the errors so far in the video, what do you think is wrong with this TI, in this case mine, so I can take a short cut? Coincidentally, mine is also a beige unit, non QI.
