For those of you who are following along with our QSIC project, today we
booted v6 Unix successfully for the first time. We'd first tried this a
week or two back but discovered that Unix does use partial block reads
and writes after all and I hadn't implemented those yet.
FWIW, so does RT11, and in the case of writes, it requires the rest of the block to be
zero-filled. Not everything depends on this, but some parts do; I think Fortran is one.
I remember this because I had to handle it in the driver for the RC11, since it has a 64
byte blocksize.
