Well I had quite a surprise today.
Returned from a work trip all fired up ready to build the Picstep boards only to find that the details have been removed from Alan's site.
It appears that someone is selling details or kits of the Picstep controller. Very Very dissapointing.
So, I have etched boards and that's it. Hopefully Alan will restore his site as thats's all I downloaded.
