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,
'AM

I have access to an EE Pac manual. Is that the same as the EE Filters Pac?

Thanks for asking - ufortunately they appear to be two different beasts, as per the listing below the Filters seems to be a "solutions book" - I suppose it was without any cards. But there are also filter programs in the EE pack, so if you could share those pages it'd be grand and highly appreciated.

Hello Ángel,
I have ~60% of the original HP-67 Solution Books at home.
Unfortunately I am currently at work and cannot check if I have this one.
I will look tonight and if I have it, I will scan the manual then send sent it to you.
Best regards,
Sylvain

Seems the manual is on the MoHPC flash drive. My bad.

Sorry Ángel,
I do not have it [the solution book] and the one on the MoHPC DVD is incomplete.
[But I have the EE. Pac 1 if you are interested. btw MoHPC DVD also have it]
Good luck on your search ....
Best regards,
Sylvain

Many thanks Sylvain, at this point I think I'll go with what's available on the museum DVD - so no need to scan/send any further.

Those programs are rather old anyway and won't compare well with more modern versions of the same subject in the 41 solution's book - at least that's what I think.

Cheers,
