Nice job, great fault finding process

[@tony359]

Very nice video and diagnostic process! Thanks for taking the time to explain the 27C256 mod - I have two ZX Spectrum to fix and that will come handy.

Many thanks!

What do you think caused the modern ULA to go U/S?. Very enjoyable repair 😄

[@HappyLittleDiodes]

Who knows. An error during previous repair may over volt it. I did that on one of my early videos and fried a vLA
