You can. I've done it with a number of Apple III disks. You should even be able to take a ProFile that's been formatted and used on an Apple III and read it on a ][ once you get the right interface card. (That's just a theory though. I haven't actually tried it.) ProDOS has EXACTLY the same logical and physical disk format as SOS did on the III's. That's not to say that once you do read the disks that the _files_ will be of any use to you. Text files are text files. You should be able to read them with no problem. Pascal type source/text files should be in the same format as Apple Pascal files are in (broken up into 2k segments, I think). You should be able to read and use 3 EZ Pieces files directly. They're exactly the same as Appleworks V 1.0 format files. 'FOTO' files are just Hi-Res screen images and are described in an Apple File Type Technote someplace. Anything else will probably pose a problem. (Speaking of which, does anyone out there have a description of the internal tokenized format of Business Basic files?) ----------------------------------------------------------------------------- Jeff Berntsen | Looking for a good .sig jeffb@world.std.com | ----------------------------------------------------------------------------- Brought to you by Super Global Mega Corp .com
