Looks like I don't have to do anything - great - I'm good at this :-)

PS you guys are far too young to know real computers. Eight 39-bit
registers in mercury delay lines, 128 'fast' 39 bit memory locations
in mercury delay lines, 8192 39-bit main memory locations on a large
magnetitic drum store. Available in 1 hour sessions, usually between
2 and 4am in the morning for junior researchers :-)
