Re: HP-41CX - 4th port Message #2 Posted by Karl Schneider on 19 July 2004, 4:45 a.m., in response to message #1 by Cyril RABIH
Cyril --
You've already "maxed out" regular and extended memory with your configuation, as well as included the best ROM made by HP. There's not a whole lot of room for improvement, but here are a few ideas:
- The Math/Stat Pac would provide a few things that the Stat Pac alone and Adv ROM together don't provide -- hyperbolics, Fourier Analysis, and triangle solutions.
Price: about US$40
- An Infrared module, along with the 822240B printer will allow the 41 to print to the same printer used by the 42S, 17B/II, 27S, 28C/S, 48S/G, among others. Price: US$100+ for Pac; US$90(?) for printer
- A Naviagation Pac provides 8 kB of useful programs for navigational calculations and celestial-object locating. Price: US$100+ for Pac
- Save it for a Card Reader or Wand? Price: US$100
- A specialty module for advanced programming and other functions: e.g., Hepax, PPC
All above prices are eBay US, not including shipping. I have all three HP modules for my 41CX, but none extra for sale.
