This user is clearly a troll. There is no point at discussing with him or her.

The luRaichu and discatte accounts are probably owned by the same person

Okay. I think I got it as everyone else. But you don’t understand you are making other users miserable by diverting threads. Really please create a separate thread about AI and why we should not use it.

Why don’t you comment on threads up to your interest ? Really I’m saddened you diverted this thread from it’s original topic. Can’t we just focus on mac related things instead of your dislike for AI ? If you really wish to make a point about AI, then create a thread about it.

@Xero Thanks for your work and for sharing it on github.

Some points to consider: - the LC 475 is small factor and lightweight, while the 630 is quite heavy and bulky - I understand the motherboard of the LC 475 is praised for its design and relatively good extensibility (for an apple product). - the LC 475 is easy to open and all the components are...

How does claude disassemble ? Does it rely on tools installed on your machine like idapro or ghidra ?

I agree an x-acto might create micro abrasions.

In my case, I cleaned the shaft and brushes with isopropyl alcohol and qtip. It was enough to clean off the black deposits. In my view the real possible damage is to bend the brushes.

I also experimented with the realignment of the head motor to solve read / write errors. See https://68kmla.org/bb/index.php?threads/fix-mitsubishi-mf355-floppy-drive.50120

I did the same procedure on the same model of motor with good results. In my case it was not working at all initially. The most delicate part in my opinion was the reassembly, specifically and quoting you “easing the brushes out of the way as you thread the shaft through” I have some tips that...

Does MacTest give you a more detailed report, like the range of address that goes bad ? Maybe that could help pinpoint what pins on the bus should be specifically checked. Have you found the schematics of the motherboard? How hard would it be to source the chips you mentioned and replace them?

Is there any diagnostic software tool that could be used in this case ? Something like a memory checker ?

Ensure the sampling rate of your logic analyzer is at least twice the frequency of your bus frequency (see Nyquist-Shannon sampling theorem) Also check the voltage of your logic analyzer is compatible. I also think you should be extra cautious where you connect the GND of the logic analyzer or...

Nice work ! Thank you for your very detailed answer. I'm slowly realizing it's quite a challenge with all the missing parts! Thanks again for listing all the alternatives. Regarding the rgb to VGA adaptator, I know some adapters like this have made for compact Macintosh. I don't how much this...
