It also occurs to me that it is remotely possible that your other disks
don't have the OS on them, although if these are ones you used in the
past, you would know that.  Can you start from one of the two "good" disks
and then try to CATALOG one of the others?  If you see a file named
"hello", "start", "startup" or something like that, try running it.  All
this is way back in the mists of time as far as my memory goes but I think
"BRUN" is the command for bin files and simply RUN for BASIC files.

Dennis most likely has provided the correct answer however since PRODOS is
a different kettle of fish.
