"Bounce buffer" copyright [was Re: flash (or ide) storage for unibus 11?]

I wrote an interleave formatter for a friend to use on his H89.
He had an enormous data file that took for ever to read in BASIC.
He couldn't believe it could be made to work so much faster.

There were a few systems (such as CP/M) that optimized (or attempted to)
interleave depending on use.  So, "boot" tracks were 1:1, "directory"
may have been 2:1 and user data 3:1.

Schemes varied widely.  One or two even interleaved side-to-side in
addition to "skewing track-to-track.  Obviously written by a programmer
tasked with the job of "Let's see how fast we can get data on or off
this thing".
