Re: Question about HP37E operation Message #11 Posted by Alex on 1 May 2005, 9:38 p.m., in response to message #10 by Vieira, Luiz C. (Brazil)
Hi Luis,
Yes I was looking for the manual because I'm not sure how the financial functions are used. The arithmetic and scientific ones I have no problems with.
I just finished putting the calculator back together a while ago. Looks nice, almost as new. While it's apart, I also clean the contacts and pads of the slide switches with absolute alcohol, that removes some grime and old dried out lubricants, and then apply a little bit of special Teflon grease. That insures long life and minimum wear on the contacts. These where almost new, I think this calculator saw very little use.
I like to use hand soap to wash the case shells and buttons because it is very mild and will not react on the lettering of the equipment, and gets the cleaning job done very nicely. I usually give any used equipment I buy the same treatment. BTW I also collect Heathkit gear, especially test equipment because I usually end up using it (have an electronics hobby bench at home), and not just putting it on the shelf to admire. Same with the calculators, they are all side by side on my desk, and nowadays I mostly use the HP41C, but from time to time, and before getting the 41, I always used the HP45. I also like to restore tube audio gear and I'm presently working on my first project, a Fisher X-202-B integrated amplifier.
Just downloaded the HP12C manual, will study it to get familiar with the financial functions. It's really more out of curiosity than need, but one never knows when some of those functions could come in handy.
Thanks for all your help, and the offer of a copy of your HP37E Portuguese manual. You're right, unfortunately it won't do me much good.
Good luck.
Alex
