Default HP calc, old school for the smart kids

I don't use my HP15c anymore and checked the prices on eBay...like $175+! Anyone here have a need for one of these before I sell it there? I have the manual and it's in near perfect condition.

I'd love to get the ebay $$, but more than happy to sell cheaper to anyone here. like $140 obo?

Is the 15 a RPN unit?

I love my 48 - still have it from engineering school, still use it.

My wife was frightened when she realized that it had 3 wire bound manuals...

I think you just answered if the "order is all messed up"

RPN = Reverse Polish Notation

Example:

2
Enter
3
Plus

5 shows up on the screen...
