Some talk of I.B.M.s and some of C.D.C.s,
Of Honeywells and Burroughs, and such great names as these,
But of all the world's computers, there's none that is so fine,
As the English Electric Leo Marconi K-ay D-ee e-F 9.
Some talk of thirty-two bit words, and some of twenty-four,
Of disks and drums and datacells, and megabytes of core,
But for those who've written usercode there's nothing can outshine,
The subroutine jump nesting store of the K-ay D-ee e-F 9.
