In the Nashville manual, after the HC ROM has been POKE'ed into RAM the instructions are as follows (p.21 Steps 11 and 12):
11. Turn the 71 off. Install CN2-5.
12. Turn the 71 on.

Then there's a stern warning about the risk of MEMORY LOST if the jumper is removed.

In the FRAM71B v1.0 manual the instructions are different (Para. 10.3, Steps 1-3):
1. POKE the HC ROM into RAM. Then there's a stern warning to NOT turn off the calculator.
2. Install CN2-5
3. Now cycle power

Also, the warning about removing the jumper is gone.

The steps have been reversed. Are the instructions for using the CN2-5 jumper truly different?

Hi,

I installed my FRAM71B today with the very very helpful installation guide from Sylvain (http://www.hpmuseum.org/forum/thread-5068.html) I did it like in his guide. Switch off the calculator activate the jumper CN2-5 switch on and continue with the installation. I let the jumper in this position after i finished the installation.

In the guide only a filename in FRAM71 Toolkit Ver 1.3 has changed: TRANS41 is now FTH41ROM

I'm very happy with my new HP71B with 4 free slots for modules. Maybe I will take some of my modules in the FRAM71B too.

Another question: what can I do with the free not used RAM in the FRAM71B?
