Apple cd drive hack
Hard disks, though highly prized, were still not affordable to most Apple II owners a 10 megabyte Covrus hard disk sold in the early 1980s cost $5,350! If someone was fortunate enough to be able to add a hard drive to their Apple II, it was still necesary to modify DOS to be able to access that drive. Third party companies produced patches that modified DOS 3.2 (and later DOS 3.3) to work with larger capacity drives, from eight-inch floppy drives to hard disks. So what advances did occur in Apple II disk storage? Between 1978 (when Apple released their original Shugart 5.25 inch floppy drive) and 1984, no improvements in disk storage came from Apple. (Actually, the way in which the catalog structure for Apple II DOS was designed would have made it possible to access a disk with as much as 400K per disk however, the low-level disk access routines built-in to DOS were only for the Disk II). As a result, DOS 3.2 and 3.3 were hard-coded to work specifically with the Disk II and its 110K and 143K (respectively) of available storage, and were never enhanced to easily access larger capacity drives. Of course, this never did happen as described in Chapter 7, the Apple III project began to overtake the hearts and minds of Apple executives by 1979, and anything newer, bigger, or better was reserved for that machine.
They answered that no, the Apple II was not going in that direction, but felt it might get a hard disk by 1979 or 1980, and possibly earlier than that a double sided, double density 5.25 disk holding 500K per disk. In 1978, the year the Disk II was released, Mike Scott (Apple’s president) and Randy Wigginton were asked at a user group meeting whether they were going to go to the larger capacity eight-inch floppy drives (which had been around before the 5.25 floppy drives were invented).
