If you are asking whether you can insert a tape, type CAT
and get a listing, the answer is, unfortunately, no.
If you are willing to write a program to read the tapes, I think it can be done, but it'll have to be in assembly as BASIC does not allow low-level access to the tape drive.
You may have more luck interfacing the HP-85 with an external (HP-IB) tape drive that is compatible with the HP-9845 tapes.
BTW anybody knows whether the 9845 tapes were read/writable by the 9825?
