I can remember when our department at work got
ONE TI SR-22
calculator and how much easier it made calculating those 48-bit
addresses and converting between bit, byte, halfword and word
addresses.
Which 48-bit machine was that?
It was a 64-bit machine, a CDC STAR-100; addresses were packed into
the lower 48 bits of a word, with the vector length packed into the
upper 16.
A tidbit that comes to mind was that it was possible for a single
instruciton to fault for 9 separate pages before it could start.
When run with 65KW pages, that was more than the maximum physical
memory configuration possible...
