Hans Wedemeyer has some L297/L298 stuff. I've printed his pcb layouts
onto some PnP Blue and am going to make my own driver boards. Email
him if you want the hex code to his PIC 12C509 smart current
controller board - he forgot to leave a link for it on his dl page.
He claims there is no problems with the drivers due to the board
layout.
