I cannot remember the name of the other RPN maker, there was at least one. This getting old really sucks, notwithstanding the limited altetrnatives. If memory serves, and I less than certain here, thery were a component maker, chips or memory I think, that did calculators for a time. Think they are out of business now.

Mr. Emerson:

"Telephonebook arithmatic" is simply a pet phrase of mine, likely I do not come close to originating it, and even if I did, it's "public domain stuff" so far as I'm concerned.

What it described as essentially copying some numbers out of a table, then doing some simple "math", plain trig isn't difficult, even I got through it, though I do not remember all that much of it. In any case, with a "scientific calculator" or "sliderule calculator", I use the HP 11C, which BTW is an RPN unit, it's a snap. I believe all HP's were RPN. I think there might have been one or two other makers that did the RPN type, which I was always more comfortable with than algebraic keyboards. Also, if I reacall correctly, some TI's, current or recent production are "selectifv fire weapons", that is you can switch between RPN and Algebraic keyboard op.

Mr. Emerson:

Concerning sight reduction, I use the USPS forms, though I have no doubt there are others, likely many others. As to the process itself, the phrase TELEPHONE BOOK ARITHMETIC somes to mind.

For the trig calculations, I use an "obsolete" HP programable calculator, the HP 11C, which is a hell of a lot smarter than I am.
