tdcheck says it's an 82 track 3.5-inch floppy image. That's seems
odd.

Anyone know for sure if I should be able to use Teledisk to write this
image directly to an 8-inch floppy? Or would I need to do something
like write the image to a 3.5 inch floppy and then use ImageDisk to
read that floppy and write it to the 8-inch floppy?
It is possible that there were excess tracks when a 3 1/2 inch disk was
added to a system with 8" drives, especially at Altos. there may not be
any relevent data on those tracks, or if there is, you may be out of
luck unless you figure out how to get a system going with 3 1/2 inch
drives and gen an 8" disk off the Altos system.
Some systems never used the 3 1/2 inch drives as a main drive, but
rather as a convenience. the system never knew there was anything
other than 8" drives attached. I recently saw that with old Computer
Automation systems, for example.
