Jim cleared it up. I was mistaken: adc_7250 works with built-in adc on every
ep93xx chip, while adc_logger works only with the MAX197 option chip on a
TX-7250 board. You don't have, and can never have, the MAX197 on your TS-7260,
but you can use the 10-bit adc of the ep9302.
Sorry for the confusion.
