AS/400 tape extraction

[Robotrontechnik]

I own an AS/400 QIC tape, formerly written with OS/400.
Now I've created a dump file of it, via DD command at a UNIX computer.
Is there a tool to extract PF's and PFM's from such a dump?
Or is there an OS/400 emulator which can mount such a dump?

There is no AS/400 emulator. It is still an active IBM product
and they would be very unhappy if someone released one
especially since AS/400 software is absolutely non-free.

Also OS/400 uses structured files with variable blocksize. Dumping it with `dd` loses all the file structure (record/block sizes) which would be necessary to create a new tape from your dump file or to understand the contents of the tape.

I think I will find a way to log also the block sizes. Lets assume I would have already done it.
How would it help for file extraction?
