nano and pico to name a few and they are all powers of 10. In

K_bytes_ or
Meg_ohms_ be there to keep some sense of If it's powers of 10 or 2.
Whats a millibyte? Saw that once!

Most of the confusion is by idiots that don't know what the fuck S.I. means.

Although
according to the author the 6502 can address 65K, not 64K.
This is very common, and is based on an assumption of 'k' meaning
1000 (decimal), not 1024 - 16 bit bus - 65535 bytes (65 thousand).
I've seen it in data sheets and other reasonably technically accurate
material - I guess it depends on your point of view (and how low-level
your experience is :-)
Hard drive manufacturers have been doing the same thing with "meg"
for years - specing in decimal 1,000,000 makes the drive sound bigger
than specing in 2**20 sized blocks.
