If you are like me, you love anything IBM, especially the PS/2 series of computers. But they make it hard to be loved. Between Microchannel architecture and non-standard interfaces and drives, it's a chore to find replacement parts. Especially if the replacement part you need is a super rare 2.88 megabyte Extra High Density floppy drive.

I was delighted to find a listing on eBay (https://bit.ly/3NlOKj3 -- not my link, not affiliated, but can recommend) for Mitsubishi MF-256F drives for the IBM PS/2 Model 90, and for super cheap at that! The hook?! "Untested" and "rough condition." No kidding... most drives I received had terribly gummed up mechanism.

Coincidentally, I recently restored a DEC LPv+ 433 (available here: https://retrobytemeister.com/products..., which had almost the same drive, a Mitsubishi MF-355. Same mechanism, same sticky ugliness needing service inside, but it's a 1.44mb PC compatible drive.

So, in this video, we'll look at how to correctly and safely service your Mitsubishi MF-356/-355 drives and give them the best chance of working!
