Mmmu_man replied to the thread Powerbook 170 not powering up.These 1N400x are meant as rectifiers, they can have high reverse voltage (400V for 1N4004, 1000V for 1N4007) and can forward 1A (50A...

Mmmu_man replied to the thread Reverse Engineering the Macintosh LC Logicboard.My LCIII seems to be okay on the plastic side of things… Maybe some batches had different sources for molding? Or maybe it's just the...

Mmmu_man replied to the thread WIP: SprintLayout (.lay6) import in OpenBoardView for logic board diagnostic/repair.Ok, trying to get the outline isn't as easy as I thought, of course it's not just a nice polygon; but a discontinuous set of polylines +...

Mmmu_man replied to the thread WIP: SprintLayout (.lay6) import in OpenBoardView for logic board diagnostic/repair.Well in theory you can also do it in KiCAD, though it may be less streamlined and might complain about missing netlist. This Hackaday...

Mmmu_man replied to the thread Pin Matrix for PPC ZIF modules?.Depending on the dimensions you might be able to replace that with things like these SMD pin headers maybe…
