We've run into a little bit of a snag with Operation DCC. Mario has done up
the TMW5 Booster board, but we're missing an IC for the decoder unit.
It's the SGS Thompson L272, a dual power op amp in a DIP package. We need
the L272M, the eight pin DIP variant. And we need one for every decoder.

Anyone?
