4     Kilburn and Williams at the Manchester Mark 1 Console

Tom is on the left, F.C. on the right. You can see the monitor CRT, propped up on a cardboard box (faithfully duplicated in the Replica!) -- presumably they had at one time expected to use a 12" monitor rather than a 6". Underneath is the bank of 8 * 5 press buttons for setting ones in a word, and then various other switches underneath, in particular for setting the page and line for display on the monitor, and controlling the operation of the machine.
