<I may be wrong, but I thought the RL01/RL02 needed a seek to even switch
<heads to guarantee the #0 and #1 head were on cyl when reading/writing.
Head 0/1 are on opposite sides of the platter so they will always be on
the same cylinder. So there are 512 cylinders of two heads, 40 sectors
of 256 bytes per track (one head/side of a cylinder).
There are a lot of ways to organize that physical layout.
