- getting closer to building our own init.

+    - get the original "init" working so that it auto-mounts /usr during

+    - we should get the /usr stuff onto the rk03 disk and get it mounted
     - can we get fpsym?
     - I don't see any mount utility in the s2 bits, we'll need one.
       - init does a mount, so we might not need one.
-    - we should get the /usr stuff onto the rk03 disk and get it mounted
     - we should see how hard it is to get the serial ttys working.
       It sounds like getting a hack working in simh might not be too
       hard, but to get it integrated back in they probably want something
       robust.  Perhaps having 1ed around will give someone the motivation
       to get dc11 support in simh?
-    - I thought "as" wouldn't work, but it seems to be trying to run
-      it.  If possible we should investigate what is necessary to get
-      the system to build its own kernel and its own tape.
     - we should investigate the original boot process and see how
       much of it would be possible to restore and determine if its
       worth the effort.
     - there's a bunch of file fragments in the 1972_stuff that might
       prove useful.  It sounds like Warren has started to think about
       how to triage these.  This might be a bit of effort.
-    - modify kernel to run 2nd ed 0407 bins.
     - bootstrap Early_C_Compilers compiler to build itself as a
       2nd ed binary.
