Fujitsu — FM Towns Marty
Thorough recap from top to bottom on this Fujitsu FM Towns Marty. The console boots and the CD-ROM side works, but the floppy drive remains undefeated. It spins but refuses to acknowledge any disk.
Nintendo — GameCube
Two spare Nintendo GameCube optical drives (DOL-001) recapped. One came back to life, one didn't. The dead one reads 30 ohms on the motor where the working one is OL, which likely points to a dead motor.
