}Here's a program which reads LBN's from a Unix/Ultrix message file, and
}translates to cylinder, etc.  This one knows about ra80's and ra81's; if
}you get an RA90 user's manual, it should have the appropriate geometry
}info you need to wire into this program.
 
     No RA90's here, but for an RA82 ...

     } else if (!strcmp(argv[1], "ra82")) {
	nscyl = 755;
	nstrk = 57;
	nblk = 1216665;
     } ...
