| Plus 800k FDD magic smoke??? |
Posted by: lostkerbal on 2024-10-21 10:02:52
I was recently working on fixing up my Mac Plus (new MoBo, RAM, etc.), and I was testing it with the case off and the FDD outside of the case, just sitting on top of its mount; it'd had problems ejecting and it was just easier for me to be able to push the manual eject. It read a disk perfectly well a couple times, but after a boot attempt, the drive started producing magic smoke, then stopped working. I'm unsure if it was the main motor burning out/getting stuck or something else, but I now have a dead floppy drive. Any ideas? Is the main drive motor replaceable? |

The floppy alone standing on top of the metal frame ? Without any protection in between ?
So probably the board got shorted by the frame. |

Can you get any high resolution pictures of the PCB on your FDD? |

So probably the board got shorted by the frame. It was standing free of the computer's frame, sitting on the workbench on top of an upside-down internal floppy drive mount. |

Could it be a similar problem I had with a SE/30 drive a while back? https://68kmla.org/bb/index.php?threads/blown-component-on-sony-mp-f75w.44807/
I tried running it without the eject motor, but this seem to kill a component (Q4) on the drives PCB. |
