Macintosh 512k floppy drive

Posted by: Macintoshguy1984 on 2016-10-03 20:51:11 I have the 97th made 128k macintosh that was upgraded to a 512k sometime in its life. Sadly the ram has gone bad so i don't have it working. I was taking it apart and I looked at the floppy drive and it had a jumper cable on it and something on the floppy drive cage that has the apple symbol and the numbers 45-0006 805-0574-b. I couldn't take the cage off today but i plan to tomorrow. THe floppy drives model number is oa-d34v and it seems like the screws were stripped out before I ever touched it.

Posted by: Macintoshguy1984 on 2016-10-04 18:03:31 I finnaly got it out of the floppy disk cage and there is a sticker on it that says january 1984

For example, during the 2nd week of 1984 this mac was number 97 off the line (for that week). But some read that as the 97th ever made, not just during that week.

Posted by: unity on 2016-10-04 18:48:02 Nice! Week 12 (about) and earlier are the first versions. After then, small revisions were made.

Posted by: jsarchibald on 2016-10-04 19:21:43 Would be a part number for the drive sled.

Posted by: Macintoshguy1984 on 2016-10-04 19:27:49 ok thanks

Posted by: Macintoshguy1984 on 2016-10-04 20:02:59 Do you Know if I were to plug this drive into a Macintosh plus would it be able to read a 400k floppy??

Posted by: jsarchibald on 2016-10-04 21:35:40 I see no reason why it wouldn't, you can easily give it a shot.  Most components are plug and play, not a lot changed between iterations apart from the logic board and the drives.

Posted by: Macintoshguy1984 on 2016-10-06 20:38:23 I tested it and i heard the motor running but then it ejected it so i tried again and it starting blinking a floppy disk with an x in the middle.

Posted by: just.in.time on 2016-10-06 21:05:35 That ejection and flashing x may be a result of an invalid boot disk and not necessarily the floppy drive not working.  Do you have any other machines you can test the disk with?
