The research that I did indicated that the BP-8 was, in fact, 9V, and my TI Programmer
calculator works fine with a 9V battery. The external power connector goes to the circuit
board, where it charges the two AA cells - this may be the cause of the confusion, since
the internal batteries are up-converted to 9V and the wall-wart doesn't power the
calculator directly itself.

I have at least 4.5V, 6V, 9V, and 12V multi-cell

THAT is what I was worried about.
The wallwart says 5.7VAC.
One of them has a BP-5, instead of a BP-8, which takes a slightly
different external power input connector.
They are claimed, so soon they will be somebody else' project.
