it's harder than you might expect, b/c the PWM routine is 'hard-wired"
into the pcode file.
basically, you have to make the changes in pcode.asm, and reassemble
the pcode_hb.s19 file.

| (...) Either I'm confused or we're talking two different animals. Our pcode_hb.s19 that came with the Gleason Handyboard, allows variable motor speeds from motor(0,-100) to motor(0,100) with great and fine control. In our first test we converted (...)
