No one has pointed out the error I made in my table for the Apple Disk ][
specs.

This should actually read:

5.25"	300	0.200	~255	GCR	~51	16*256	35/1	140	SSDD (1)

This is because the 65(c)02 rus at slightly more than 1MHz, not less. The PAL
Apple // actually runs a tad slower and writes disks at approx 254 kb/s.
