Hi Matt

Have you thought of replacing the MOSFETS on Dan's board with some
opto-isolator chips and using te output from these to drive a high voltage
bridge ?
I know it involve a bit of messing around, but there are plenty of high voltage
FETs to choose from, or even IGBTs.

Jst a thought, doesn't the BOSS motor drives have a set of inputs from an
external step sequencer ? It may be possible to use a PBD3517 to drive the BOSS
boards direct.
