BTW In the 50s or maybe 60s IIRC Ferranti invented 'virtual memory'.
They sold the idea/patent to IBM. They were simply 40 or so years ahead
of their time for mass usage.

"Also, Burroughs independently released in 1961 the first commercial
computer with virtual memory, the B5000,[5][6] which used segmentation
rather than paging."

The Wiki article doesn't mention Ferranti.

Horrible idea anyhow. Virtual memory is the main contributor to poor
data structure design and code bloat, not to mention things running
about 20x slower than they should.

Hour incredible nationalism is silly and largely wrong.
