What model was it. Not an 803 or 503 by any chance?

I learned to grapple with mainframes on those. But I was recently surprised to learn that I had also encountered the same machine in a tiny box on a Nimrod aircraft! There was a military version of the same great big computer that fitted in a small box, dedicated to processing radar. Again showing that the reason for the big machines in many caninets was maintainance convenience and ease of replacing modules. If you really wanted small and light - you could have it!
I have a vague recollection that it was an ARCH 101? I know Elliot was associated with GEC and I think some of the process operators went down to Borehamwood on training courses.
