I unpacked it and found that disk 2 is the wrong size - it's too big for a disk image (145,400 as opposed to 143,360 bytes). Booting "side 1" asks for "side 2," and if I truncate it to 143,360 bytes, it doesn't work.The "Giant_World_Side_B.dsk" image is pretty messed up. The beginning of it is definitely not a disk image, and the last few "tracks" are actually a nibble image, not bytes. In between, there is clearly some recognizable data, but there's also a "giantb.dsk"--which almost certainly is unrelated to the original disk image. Looks like a do-over is called for. -michaelI'll take a look at it. They do run extremely well (if no transmission corruptions) with the AppleWin emulator. giantb.dsk is the name the dsk usually has. I gave it the longer name so it would not get lost in all of asimov's listings, but, by alphabetical order, stay with the documentation, etc. It is possible this was a disk image generated with the 2inaPC emulator's data transfer program -- that always added a prologue (I - think- it was a prologue) that increased the DSK's size.If you have an image that runs correctly, just re-zip it and reupload. That should put it right. -michael ******** Note new website URL ******** NadaNet and AppleCrate II for Apple II parallel computing!

Perhaps this weekend, if it is that simple. Interesting how even a "wierd" image is running okay. One of the features of AppleWin is that it is not fazed by ProDOS ordering versus DOS ordering in its disk images -- if you give it the wrong one, it just switches over. Perhaps the AppleWin emulator is really very versatile in accessing disk images, even overlooking the 2inaPC prologue that is apparently there.
That is certainly not the case with the image in the .zip file you uploaded. I'm guessing that the "side B" image you are using is your local copy of the image, which is apparently OK. -michael ******** Note new website URL ******** NadaNet and AppleCrate II for Apple II parallel computing!
