The manual for the TI programmer describes the battery pack (BP8) as nickel-cadmium; when
I checked my (dead) battery pack, there appear to be multiple cylindrical 'cells'
within the pack itself, but there is no mention of the voltage rating and - since my pack
is no longer functional - I can't measure it for you.
From this article [http://datamath.org/BP_Repair.htm]
it appears that the external adapter was 9V and the battery pack uses some form of
inverter to generate 9V from two cells. [http://www.rskey.org/CMS/index.php/the-library/8]

I just tried running the calculator with a fresh alkaline 9V battery and it works fine!

9V, or just using that connector?
I have one working, and one dead. Anybody interested in them?
Note: this is the original LED one (with short battery life), NOT the LCD
one (with short keyboard life).
