The paper in the IBM Systems Journal says that the 7040 had a disk which they
used for spooling. The 7090 had no I/O devices other than an interface to
transmit blocks of words to or from the 7040 and interrupt it.

It wasn't just spooling.  The paper said the 7040 did a lot of other job scheduling
stuff that operators used to do.

Somewhere I read that someone switched the two machines so the 7090 did the I/O stuff
while the slower 7040 did the computing, and the whole system ran faster.
