Vintage Apple Hard Disk 40SC (Conner CP3045) pulled from a Macintosh Portable, Apple’s first laptop from 1989. This is the rare proprietary version with the 34-pin connector made specifically for the Portable.
It used to spin up without issue, but it’s been roughly 10 years since I last powered it on, so I’m selling it untested. It looks clean with all original labels intact and comes complete with the metal mounting sled and ribbon cable.
Great for anyone restoring a Mac Portable or needing the correct sled/cable for a custom install. Sold as-is.
