Only in the sense of "misuse" being that

probably close to 255. For example, the Intel MDS800 "double
density" MMFM format uses 0B with a clock of 70 for a DAM or 08/72
for a DDAM (deleted DAM).
Most controllers can support DDAMs but few operating systems actually
use them. Most often, you see them used on the cylinder 0/track 0
volume header used by IBM 3740-compatible formats.
Yes, there are plenty of valid uses for them.
But, I'll stick with calling Superbrain a MIS-use.
What did it accomplish?
In the case of TRSDOS, I think that I get what Randy Cook had in
mind, but he never completed code for that use to actually do any good.
TRSDOS3 and VTOS showed that he was capable of starting incredible
projects with little hope of finishing them.
