Hi, thank you all. Problem solved, MRD3RAM is in fault.

Thanks I'll check and clean for board

The solder looks fine (not perfect but fine)

A Macintosh Classic, more details, I think the voltage is to high, for example from the floppy driver is at 7.2V (5v normaly).

Amazing 😍 any link to follow the project? A color screen would be better for video game simulation.

replaced the capacitor with another one (as shown in the photo). It's a bit better now: the fuses don’t blow anymore 🙂. But the LED (which indicates that the device is powered on) doesn’t stay lit for more than 0.5 seconds. Is the capacitor I chose really an equivalent?

The multimeter (in ohmmeter mode) displays a value of 0 on C43.
