Macintosh SE/30 Fixing Motherboard Faults.

I spent many months (eight) to repair some of these macintosh SE/30 motherboard, like you can see in the gallery.

The flaws that i could find and repair are:

• Some multiplexers (74F253 or like) burned.
• Some Video Ram burned.
• Very Dirty Motherboard.
• Electrolytic capacitors have to be replaced.
• Reseat the RAM and ROM SIMM.
• Some track of the PCB broken or corroded by the acid.
• Replaced the lithium battery with a new one.
• Cold solder joint on chip: RP4/RP5/RP6 – UI2/UI3/UI4 – UJ2/UJ3/UJ4

The flaw that you see in the first picture and that should be the “Jail Bar Pattern” or “Smile Mac in Jail”, in this case is not been so. For this reason i spent a long time to find the fault.

However, i recovered 3 motherboards and I consider myself quite satisfied.
