Yes there are age problems, but right now I have managed to get the spinning media working on all the machines I work with, it was not that difficult. Yes the media is failing but the stuff that I have that is new or was taken care of is still working for me. So while it works I like to show it. Maybe another 10 years? Maybe more.

We cannot keep the hardware functioning for 10000 years, or even 100 years. There are rubber and plastic components in a lot of this stuff, and they are slowly deteriorating, depolymerizing, and falling to bits.
Our only hope in that are is that accessible, inexpensive, low-volume manufacturing techniques, such as 3D printing, mature quickly enough for us to be able to replace those components.

My view on this is not the fact that we are in able to keep the HARDWARE functioning. We can keep that maintained for 10000 years. The magnetic media utilized by the disk drives have been reaching their end of life, NOS boxes have been opened, used, and found to be damaging to the hardware as the media is sloughing or flaking off the Mylar of the disk itself. So the question becomes restoration vs visual preservation while not losing logical functionality.

My $.02 Aw, lets be careful about that. I like the convenience of the SD card file systems and they have their place, but working disk drives are important to the demoing history. This was clear to me at NY Maker, and also was commented to me by several individuals at VCFE. If we can't keep disk drives going, we might as well admit failure on the whole restoration scene.
BTW: I think the IBM PC boot drive is bad too or the DOS floppy in the drive is bad. It boots right into ROM basic.
