Photoshop no longer reads IFF images, although there are other programs
that can.

Nothing that I know of can read the images that were produced by an
Apple ][ based graphics system that we used around 1980. There are many
custom graphics setups from that period whose output will be lost unless
somebody managed to convert it in time.

Even reading cp/m data disks at all is very difficult. 

And we are talking about a period that is considered quite recent in
audio recording terms.
