The internals of my Atari Stacy, the first portable computer from Atari. Made in 1989.
The hard disk was broken, the bearings seems to have broke because there was some kind of sticky fluid leaking out of the hard drive. I bought a unused IBM-drive from Ebay, unfortunately it was half height and thus didn't quite fit inside the Stacy so I had to remove the floppy, and the Stacy wouldn't detect it (it worked with my TT). So I ended up mounting the old one again, but without the power connected and replaced the floppy drive, which was broken.
