If we're gonna have a war over who's pedantic, you've got a long
way to go, kiddo. :)
143K? Only if you're a HD manufacturer or a brainwashed metric type
who counts 1K as 1000, and 1M as 1000^2. Computers happen to use 1024,
so the 140K figure is far more correct. A //e has 64K of memory, which
is actually 65536 bytes, but it's sold as a 64K computer, not a 65K
computer.
In other words, let's do the math: 256 bytes/sector * 16
sectors/track 35 tracks/disk is 143360 bytes/disk. That number is
fixed and correct for all normal disks (we'll ignore extra tracks that
could be hacked in for now). 143360/1024= 140K in the computer sense
of K, not the metric.
