For sale is a Apple Macintosh SE/30 logic board. This board has been fully tested, carefully cleaned, and professionally recapped. The original SMD electrolytic capacitors have been replaced with modern tantalum capacitors, the axial capacitors have been replaced with new equivalents, and the board was thoroughly cleaned after capacitor removal to eliminate any remaining electrolyte residue. The board shows no battery corrosion and required no trace repairs.

Cosmetic condition is good overall; the PCB is clean, components are intact, and the SIMM sockets and connectors are in excellent condition. Based on the serial number (SG9354PF198A), this unit was manufactured in 1989. Please review photos carefully for exact condition.

It comes with 8MB of RAM installed.

As with all vintage Macintosh hardware, reliable operation requires a healthy analog board, power supply, and properly functioning peripherals. Please ensure compatibility with your system before purchasing.

Fast and careful shipping from Tokyo, Japan.
