HP BASIC (Series 200/300): Detokenizer

[Michael Fehlhammer]

I received a question from a person who has some floppy disks containing HP BASIC programs; He wonders wether it is possible to read these programs on a modern PC.
The first problem can easily be solved: A program like HPDir or the old LIF Utils can help to copy the files from LIF to FAT (DOS) formatted disks.
But then: The Basic programs normally were not saved in ASCII - Format, but in tokenized PROG format.
So the question is: Is there a de-tokenizer program available ( for free, preferably) that translates HP series 200/300 BASIC (version 5 or 6) programs into simple ASCII text? I faintly remember that I read about such a tool, but where?
