COGO program for HP15C

[Geoff Quickfall]

Firstly, a little humour here,

Secondly, and I quote DB:

"sometimes a guy with a field book, a #6 pencil, and a 15c to figure his cuts. It's a science AND an art."

As far as precision and program ability the 15c is still magic. Albeit not in the league of 41C and greater. But that is mostly due to the greater memory capability of the others and convenience of alpha numeric prompting and storage (onboard, external).

I can honestly see a 15c, plasticized field book and pencil working very nicely. But then, I am from the era of the slide rule, plasticized field book, pencil and simple transact science, so anything greater then the slide rule is magic.

I guess, if he is comfortable with the 15c, then fine, and yes the 41c and greater are more convenient but I would not say the 15 is a joke except in humorous vane.

There are many postings about favourite calculators, just search the archives. It seems the machine you first picked up became your favourite. If it was RPN, then RPN; RPL, then RPL; PRIME, then prime.

If your first programming experience was RPN, then for many it was too big a jump to go to RPL so the 41cx is it. It can be argued that the 41C series too is a joke when compared to the dedicated RAMs in a 48SX/48GX.

IMHO. :-)
