True enough I'm sure. MITS also produced a "mini"-floppy controller that
was also a two board TTL set. The first board (computer interface) was the
same board as in the 8" set (except for different RC values), the second
board was completely different. I have the MITS docs for the "mini"-floppy
system and it is documented as a hard sectored using 16 sectors per track.
I also have an Altair Mini-Floppy BASIC disk and it is also hard sectored
with 16 sector holes.
