Yup. There was even a Mini-UNIX distribution for the 11/10.  One of
the more appalling things about it was that there wasn't enough memory
for a static partitioning between kernel and "user" code.  User code
was linked to start at the end of the kernel.  Changing the kernel
usually meant relinking the entire userland.  Not fun.
