Performa 410
Also known as the LC II – A Mac for the masses.
The LC II was a modified version of the earlier LC. Running a 68030 32-bit CPU on a 16-bit data bus and hard limited to 10 MB RAM maximum, with virtual memory support, it’s slower than the older Mac IIx, despite having the same processor.

At this point, the board was cleaned extensively using cotton swabs and isopropanol.

At this point, I lost one of the capacitors somewhere in the carpet, and discovered I ordered the wrong voltage of another. Ordered new parts and waited a week.
