It's easy enough to look at block 1 and be sure... There are lots of slips possible when Apple II tools are used to capture/transmit Apple /// disks, since you can be pretty sure that the images have not been verified to boot SOS since originally being archived. -michael
OK I looked at Block $0001 on the Apple /// System Utils disk. It was just full of zeroes. However, Block $0000 is exactly the same as Block $0001 of the ProDOS disk. So, I copied Block $0000 of the Apple /// disk into Block $0001 of the Apple /// disk, but I still get the IO ERROR.
Then I tried this: I copied Block $0000 and $0001 exactly from the ProDOS disk to the Apple /// disk. Still, IO ERROR.
If I try to boot the Apple /// from the ProDOS disk, it gives a different error: SOS KERNEL NOT FOUND.
The weirdest thing is that in Block $0000 of the ProDOS disk, line 010 says the first part of my e-mail address: "JJJ.@.I" What the hell?! How could my e-mail address be in there?
I am guessing that somehow my FTP program is messing up the disk images, since why else would part of my email address be in there? Or is it just the weirdest coincidence of all time? I'm just using Fetch to get these DSK files from asimov.net. But why would it put part of my e-mail address but not the whole thing?
It's only on the ProDOS boot disk. But also I formatted a blank disk with ProDOS and "JJJ.@.I" is also on that one! I'm putting my money on crazy coincidence...
Incidentally I noticed the Kernel file starts in Block 7 on the Apple /// System Utils disk.
Anyway I'm at my wits end here. Maybe you can make heads or tail of this. -JJJ
