** Going to 1 person shifts - work it out with who you are on shift
with for this cycle. Until this week end. See sep. message.

The problem of the inoperative xerox machine persists. It has been
suggested that this will be a part of the KAMI upgrade. However, we
hope for some kami beam just after the ketv run, so perhaps the
xerox upgrade could be moved forward to also be useful during
KTeV. Would that be spinn-on? ( if useful things coming after or
is spin-off? ).
