How many bytes are there in a MegaByte? (was: OT: how many heads, Cylinders on a Quantum 540?

Three people (I was one) posted the specs of the Q-540, which may or may
not be the 540 that Richard asked about. The Quantum GoDrive540, and
Quantum ProDrive540 are DIFFERENT specs entirely with more than 10 times
the capacity.

> If you mean a Q540, then Spininfo says 8 heads, 512 cylinders, RWC = WPC
> = 256, FH 5 1/4", 36 Mb, MFM.

> Model Interface Capacity Cylinders Heads Sectors
> Q540 MFM 36MB 512 8 17

BOTH of the references quoted call that "36MB".
Simple arithmetic:
8 * 512 * 17 * 512 gives 35,651,584
IF a megabyte is 1048576, then that is exactly 34 megabytes.

EVERYBODY here is capable of doing that multiplication.

Are we going to completely give in to the SLEAZE and redefine meg as
1,000,000, and K as 1,000?


Q: If IBM ran a donut shop, how many donuts would there be in a dozen?
