Another faulty chip to the Camel ash tray! 😄The tips about what we should be seeing on a functional z80 are invaluable Mike, thanks for another great video 👍 and great fireball jump on the test play haha

Yay! Another DK repair. It's fascinating that all the board you repaired had different kind of faults. It must be fun to work on them?

It's amazing how many different ways things can fail. 😀

What’s your thought on the chip tester. Been meaning to buy one and first time seeing it being used. Thanks for videos, you’re helping the community out!!!!

I love the chip tester for validation if nothing else. It has been pretty accurate too.

The Bad LS14106 HEX Schmitt Trigger does what to the RESET circuit?

[@MikesArcadecom]

Probably a delay or something. Just guessing as i didn't look.
