I was directed to this page as a general interest but on page 47 an
explanation about what happens there may be of interest. If you need
some bedtime reading, a history of the program machine on LU might

Looks like it will be an interesting read when I've got more time. I hope
it's nothing to do with the hold up on Putney Bridge on Friday which nearly
caused my daughter to miss her Eurostar.
