Apple Disk IIc

역사적 배경

The Disk IIc (A2M4050) was a half-height 5+1⁄4-inch floppy disk drive introduced by Apple Computer in 1984 styled for use alongside the Apple IIc personal computer, the only Apple II to contain a 5+1⁄4-inch built-in disk drive mechanism. The disk port on the original IIc was only designed to control one additional, external 5+1⁄4-inch disk drive, and as such, this particular drive omitted a daisy-chain port in back. It was possible to use it on other Apple II models, so long as it came last in the chain of drive devices (due to lacking a daisy-chain port); but since the Disk IIc was sold without a controller card, the Apple IIc computer needing none, it had to be adapted to an existing Disk II controller card in this case. Essentially the same as the full-height Disk II, Apple sold the Disk IIc for US$329.
