If the gain is 2, it's not interesting for me. If it's a factor of 20 or better (that is down to 10uA - about the same level of the bare HP-71B), I may be interested!

standby current on FRAM71B will be down from 150 µA to approx. 60 µA. very early FRAM71 (non-B) prototypes got indeed down to below 10 µA, but that was at the cost of the SYSRAM feature. if you _really_ need the reduced current consumption on your FRAM71, drop me a mail Smile
note however, that it takes about 17000 hours (more than 2 years) for an FRAM71-512 to bring down a fresh battery pack to a LOW BAT condition.
higher standby currents are more problematic when it comes to battery changes and associated "brown-out" times. but then again, that can be easily mitigated by having your HP-71B connected to an AC charger while changing the batteries.
