For the final day of #DOScember 2025 I give you part 4 of my #IBM5150 restoration video series. With lots of help from the community, I try to trace down what IC(s) are keeping my IBM 5150 from booting.
The IBM 5150 will return in 2026 for Part 5!
Happy Jank-tastic New Year!


Something seems off with the AMD 8088 CPU at U3 on my #IBM5150 that I am trying to restore for #DOScember.
Pin 22 Ready should go HIGH when the CPU is ready to start executing code. The view on the oscilloscope shows high then low. Not good.
