Philips X1215 Imager
The Philips X1215 Cartridge Disc Drive stores a whopping 2.5 Megabytes on its internal fixed disk, and another 2.5 Megabytes on a removable disk in a cartridge. The drive takes 40 kilograms and 1200 watts of power to do so!
I want to get one of the X1215 drives I have back in working order, and build an interface so that I can make images of all the disk cartridges I have.
