Hardware
The 20SC originally contained a half height 5.25" Seagate ST-225N 20MB SCSI hard drive, but was later manufactured with a full-height 3.5" MiniScribe 8425SA 20MB SCSI hard drive. The latter drive was the same size as the drive inside the Macintosh Hard Disk 20, but 10 to 15 MB over what had previously been offered by Apple for the II family. The same drive mechanism would also be offered 6 months later as a built-in drive option on the
Design
In addition to being the first cross-platform drive offered by Apple it was the first hard drive to use the Snow White design language. Notably, it was the only Snow White product to use the Macintosh beige color and one of the few Apple products to be introduced in two different colors at the same time. Since the Apple IIGS was the first Apple product to debut in the new gray color they called Platinum, the 20SC had to both match it and the beige color of the Macintosh Plus, which it is designed to sit perfectly beneath. In 1987, all Apple products would change to Platinum, which would remain in use for the next 10 years.
