HP-41cx educalc module? - Michel - 02-27-2002 I found a working hp-41cx and there is a strange mondule (for me...) install in it : on the back of the module a silver tape label "EDUCALC MODULE SERVICE" and on the normal place for module labeling another silver tape label "Double - A531D" What is that module and how to wake it up? Is it "homebrew" module? What is educalc? ok, i stop...
Thanks for hints!
Re: HP-41cx educalc module? - steve - 02-27-2002 Educalc was THE mail order supplier of HP calculators and accessories for many years. They were located in California, USA. About 3 years ago, they went out of business (since HP started selling through large retailers). As far as the module you have, I know that service modules were made by HP to diagnose 41s with problems. But I did not know Educalc apparently made some. Perhaps someone else may have seen/used one of these modules. If you do a CAT 2 it should list the programs on the module. Steve
No program on the module with CAT 2 - Michel - 02-27-2002 I tried CAT 2 and no program for this module
Re: No program on the module with CAT 2 - Bill Duncan - 02-27-2002 Try a different port. Turn the machine off, pull it out
It might be an autoexecute type of module too, like the are you doing this from a c/cv or a CX ? - Thibaut.be - 02-27-2002 Note that only a C or a CV will list the programs with f CAT 2; the CX will just list the modules and ROM's installed.
Hoever bill's remark is totally valid, should the module not being recognized try another port.
Re: are you doing this from a c/cv or a CX ? - db (martinez, ca.) - 02-27-2002 jim had some deal to double up x-mem (and other) modules in the same case to save ports. this may be one of thoes. check how much extended you have; if it's all 600 then you have one of thoes.
Re: are you doing this from a c/cv or a CX ? - Chris Catotti - 02-28-2002 I assume it added EXTENDED MEMORY also. Check it on a CX with CAT 4. Should show 124 in the X Register. With one EXTENDED MEMORY MODULE, 362, or two EXTENDED MEMORY MODULES 600. You can also check it on a C or CV with the EXTENDED FUNCTIONS MEMORY MODULE by executing EMDIR. David White (now David Ebras-White) use to do a lot of the soldering foe EduCALC and authored the "Butcher's Block" articles in the PPC Journal, which included a description of module doubling and tripling. See: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=2005484928
for a little longer write-up
cat 4 = 600 - Michel - 02-28-2002 I try cat 4 on my CX with the module and it gives me 600; without the module it is 124 so this is a memory module sold/built by educalc... Thanks all!
