Replacing the board would've been $600.

My HP 45 calculator developed a bad display. I removed the 00 size
phillips screws, opened it up. and relaced the LEDs with a Radio Shack

My 48G is made in Singapore. But, it's like my right hand, I have to
have it! I like having four stacks visible for one thing. And it
graphs. I've had it about 14 years or so, and it pains me to have to
use a calculator that doesn't use Reverse Polish Notation.
