Re: [CAD_CAM_EDM_DRO] Re: Higher power from L298 etc.

This makes me wonder what the status of the Gecko high power L298
replacement. For those that don't remember Mariss said he would put together
a design that used the power output section of a G201 (80 v 7 amp) and on
the logic input side worked like a L298. I think he mentioned a price of
$20 - $30 per unit.
