HP-UX 10.20
Application Software
HP Integrity and HP 9000 servers.

7xx server series. June 1999, with OS install

The OS disk is for the 7 x x series

Plus

8xx server series. Sept 1998, with OS install

The OS disk is for the 8 x x series

For the applications these are ISO images burned onto CDs not the original disks. 

The unlocked application disks were for internal HP Applications engineers. Please look at the picture where it says ALL SOFTWARE ON THIS DISK IS UNSECURED. (left side under the date code)

Finally I have a HP-UX IO libraries disk that is super useful for running instruments.
