Welcome to the Jeff's Calc Page !

This is my home page devoted to calculators, especially the HP-41C and the HP-71B. The HP-41CV was my first "serious" scientific programmable calculator, but the HP-71B is still my favourite HP machine.

This page is still very basic, and will be upgraded from time to time...

At the moment, you will find:

HP-41:

• my emu41 page
• 560 digits of PI with a HP-41C

 

HP-71B:

• my emu71 page
• HP-71B bugs page
• JPC ROM page
• Math ROM page
• FORTH/Assembler ROM page
• my emu72 page

HP-IL:

• my HP-IL resource page

Other HP machines:

• my emu75 page (HP-75C)
• my HP Portable Plus resource page

 

Documentations:

 

• French resources (JPC, PPC-T, manuals, ...)
• Miscellaneous documents
