The Hobo Camp Fire Is going well #VI.. Stop In!!!

Well I've been studying the copy I made of the SDFloppy II SD card. It has sixteen directories, numbered 0 thru 9 (1-10) and A thru F (11-16). Each directory consists of one (1) .DLL file and one (1) .DSK file and can hold the equivalent of one 5.25" floppy diskette. So one SD card can comfortably hold the contents of sixteen 5.25" diskettes. Disk utility programs that do a sweep of the file table contained in the .DSK file can display a list of the files when the user (me) uses the Applesoft command 'CATALOG' (same as 'DIR' in MS-DOS). However programs that look for track $11 (track 17) specifically can't display a list of the files nor can they copy files to or from the SDFloppy II. Copy 2+ is one of these utilities. The DOS 3.3 programs of the 'SYSTEM MASTER' utilities can work with the files all day long with no problem and can copy to and from the SDFloppy II just as if it's an Apple Disk II disk drive. Copying a diskette to the SDFloppy II is slightly faster as there's no delay waiting for a disk drive to come up to speed and index to the proper physical location of a diskette. I say slightly because the Apple IIe's processor speed is only 1.023 MHz so it can send data through the drive interface only so fast and the speed of the interface is also very limited. It can also INITIALIZE (format) the allocated space in the directory just as if it's a 5.25" diskette. I'm finding it to be a handy little device.
