| Performa 450 restore |
Posted by: Andrew18489 on 2022-05-30 13:22:34
I’ve been working on restoring a Macintosh Performa 450 for a long time now. I’ve had one problem after another. Today while attempting to install the internal version of the BlueSCSI, something went wrong. I guess it’s been terminated and doesn’t need to be because the floppy and mouse quit working. I thought I fixed that earlier, but I guess I was wrong. Before I realized the problem, I tried to put a floppy disk in the drive. It didn’t work, and I thought I’d put it in the wrong way. Because I have an automatic floppy drive and didn’t know it wasn’t even running, I attempted to remove the disk myself. It didn’t work. I realized my problem too late after jiggling the disk around too much. Now it’s jammed, and because I used pliers and got it partially out already, I assume my floppy drive is now damaged. I have a spare 1.44mb floppy drive from a PC, but it doesn’t have the same floppy connector. are the read/write heads replaceable? do I even need the second drive’s parts or can I just salvage the first? Why if I thought I’d fixed the termination issue on the BlueSCSI did it continue to persist? |

You'll need to get another Sony MP-F75W floppy drive. The PC drives are a different bird. |

I took a box of Macintosh parts to uBreakiFix. They couldn’t help me with the BlueSCSI soldering, but they did remove the disks from the drive, and at no cost. I brought the floppy drive home and tried it. It didn’t recognize that I was trying to put a disk in it. I don’t know if it comes on or not. Given the price of a new drive, I’d at least like to try to repair it myself. I found lots of information, but I’m just wondering where to start for a drive that’s not recognizing the floppies (and probably not going to read them even if they’re recognized) without repair.) |

The eject drive gear you can get them here for about $10. As far as the soldering of the BlueSCSI I could do it for you I've done it myself multiple times. |

Is the gear 3D printable? |

Is the gear 3D printable? Yes but you need a very, very good 3D printer most cannot print this at all. |

Does the drive make noise when you power on the computer? I’m first of all curious if it’s dead. |

I’ll think about what I want to do with my old stuff and decide later. |

I’ll think about what I want to do with my old stuff and decide later. I don't mean I'll sell it so long as you cover shipping it's yours. I do believe the floppy you have needs the eject gear replaced its very common on these. As far as your BlueSCSI have you done any soldering before or do you have a Soldering Iron? |

I didn’t do the soldering. Someone else soldered that BlueSCSI for me but it had issues. A wrong resistor was installed and another member commented about the jumpers. |

To answer your earlier questions about using PC drive parts on Mac floppy drives, no that won't work, they are not the same.
I've had a very varied experience with getting floppy drives working at all. There are lots of factors at play. Disks can be bad which damage an otherwise good drive. I don't mess around with floppy drives anymore - I use a Floppy Emu if I need to load a floppy image on a Mac, they are not the cheapest thing out there but they are well worth the money and make life so much easier. Otherwise, someone on here may have a working drive and be able to send you some working floppies to go with it (that said, doing a system install from floppy disks alone, for anything other than early System 7 is not a fun experience).
Whoever did the soldering on your BlueSCSI screwed it up, that BlueSCSI is not going to work without some serious soldering rework, get a refund and buy one that's been done properly. Or buy a ZuluSCSI instead (it's a better device anyway and the cost is not much more). |
