A tangential question out of curiosity: 
who here has 5.25" MFM drives they're 
extremely surprised are still working, 
and which model(s)?

I'll start.  I've quite a few MFM 
drives, but the ones that really 
surprise me are (2) Seagate ST-506, and 
(2) IMI CM-5412.   My surprise is b/c 
these are amongst the earliest of models.

I've performed *some* work on all these 
drives, such as cleaning and caps 
reforming, but haven't yet discovered a 
way to lube motors & bearings.   I think 
lube issues will spell their ultimate 
demise.
