Day 068/23. This is the ICL 2900 computer.

A visit today to the Museum of Computing in Milton Keynes. I used to work on these, many decades ago. Well, not on all of what you see, on the tape drives. It's the cabinit in the middle at the back. This computer is approaching 50 years old.
The disk drives on the right are 80MB per cabinet. For comparison, my camera takes a single picture that is 22MB, so that big cabinet can only hold 3 of my pictures from today's camera.
The ICL 2900 Series was a range of mainframe computer systems announced by the British manufacturer ICL on 9 October 1974. The company had started development under the name "New Range" immediately on its formation in 1968. The range was not designed to be compatible with any previous machines produced by the company, nor for compatibility with any competitor's machines: rather, it was conceived as a synthetic option, combining the best ideas available from a variety of sources.
