hp-67 EE Filters pack manual

[Ángel Martin]

I'm considering putting together the 67 EE Filters pack into a module - which seems quite an easy task considering that all programs are available as RAW files in the museum, see:

http://www.hpmuseum.org/software/soft41.htm
approx at the middle of the page section "HP-67 Filters Solution Book (Ported to HP-41C) "

However I'm not all that happy with the direct port from the 67 code, a tad crude in data entry and result output for my taste. Does anyone have access to the original manual, so I can figure out the program flows and try to improve on them? Only then I think they'll be a valuable addition to the 41 community (and the CL of course).

Thanks,
