Apple Hard Disk 20SC, Model M2604. After 30 years, it is still sealed in its original plastic bag. There is no yellowing whatsoever to the original platinum color of the case.
In my opinion, you are unlikely to find another sealed Apple Hard Disk any time soon. This is the last Hard Disk from my personal collection of vintage Apple Hard Disks.
The original box and styrofoam packaging are in very good condition. From a smoke-free, climate-controlled home. Buyers from the lower 48 US states only.
