The Apple Disk II analog board has a couple of toroid cores on the
board; does anyone know what the permeability is, or better, what would
be the equivilent Amidon number would be?
Also, if anyone needs some of the boards, let me know. $5.00 including
USPS priority mail (they supply the box!) for up to 1 pound of boards in
the US :). These are untested pulls.
