I've added code to mkfs7 to build a free block list, to write it out to
...
the disk image, and to add a pointer in block zero to the beginning of
the list.

I've made a start on a mkfs tool for PDP-7 Unix. So far I have the routines
...
to build the filesystem, but they are not tested. I need to add code to
parse the "proto" file, whose syntax is based on the 6th Edition proto file.
I also need to dump out the filesystem image.

Very preliminary B compiler. Only able to compile hello.b and not
tested further. This is implemented in a subset of C that will
hopefully ease porting itself to B.
