  1. Hello I have a bunch of Sony MFD-51W 800k floppy drives that I'd like to put back into my Mac Plus computers so that I can sell them. Fortunately, I was able to get all their eject mechanisms working properly, thanks to James Wages' terrific instructions!

  4. As many of you know, there is a small eject gear in 800k floppy drives which often breaks, and I've seen some replacements sold on EBAY. The only auction I could find with a reasonable price for the gear and reasonable international shipping (to Japan, in my case) is this: PMMA plastic in mold: https://www.ebay.com/itm/Apple-Macintosh-1x-GEAR-for-800K-or-2M-SONY-FLOPPY-DRIVE-MP-F51W-MP-F75W/333463751453?hash=item4da3fd0b1d:g:1ucAAOSwhQhY0iTg Here is an auction with a reasonable product price but which sadly doesn't ship outside Australia, and no plastic material i
