CFFA300 and Apple III

Mike, I read the relevant chapters and have a bit better understanding of the Apple III...I think. I tried making an SOS disk today using my Apple IIe and the CFFA3000 with some Apple III dsk images i found online. I used ProDOS and was able to format the floppy and it appeared to copy the image onto the floppy. At least it said it was successful, but when I tried booting the III with it, the drive spun for about 3 seconds and then stopped and nothing else happened...nothing on the display. Should it work to copy a floppy like this using ProDOS on a IIe for use on a III? Is there another utility that would be better suited to copy the disk? Thanks, Win Unlike the II, which is relatively easy to configure to boot to any (bootable) storage device in nearly any slot, the Apple III tries to boot only from the internal floppy drive, and as Eric pointed out, you'd have to roll your own ROM to change that behavior. The CFFA3000 works nicely in the III, but you lose the Drive ][ emulation capability and you can't boot directly to it. In the Apple III, everything is seen as a device and requires a driver that SOS loads as it boots in order to be accessible to the system during operation. You can't (easily) boot directly to the CFFA because SOS requires a driver to be able to recognize it. Fortunately, SOS is close enough to ProDOS that you can use the CFFA in an Apple II to create floppies from the images you downloaded. I'd suggest reading this PDF for more on how the III works: http;//apple2scans.net/scans/manuals/3rd.party/OMHGYA3.pdf It's the Osborne McGraw Hill Guide To Your Apply III. Pay special attention to Chapters 3 and 4. LMK if you have any questions about all this. - Mike
