Fortunately he is planning to upgrade HPDir anyway, and he is willing to extend the tool to meet the needs of us calculator enthusiasts.
What he would like to have is an initial version of such a file type data base....

Excelent news Michael, thanks for motivating Ansgar on behalf of us calculator fans. Only this past weekend at HHC in Reno we had a discussion on this exact topic - how to extract from or add into a LIF archive file - for use with 71, 75, and 41. I did recommend HPDIR (with links to the site) but noted the limitations of the "file type" and "implemetation bytes", which are the 2 items you have described (I believe). Having these improved in a new version of HPDIR would be quite useful for manipulating LIF files.

Where should information on requested File Types / Implementaiton Bytes be sent? Should suggesitons simply be added via post here, or are you collecting them, should they be sent to Ansgar, etc?

Good news indeed, thank you for sharing this news and for helping to make these improvements possible!

Edit: I just knew Dave would beat me!
