- Per Wikipedia:
The initial model, the Cray-1A, weighed 5.5 tons including the freon
refrigeration system. Configured with 1 million words of RAM, the
machine and its power supplies consumed about 115 kW of power; cooling
and storage likely more than doubled this figure.
The Cray-1 was built as a 64-bit system, a departure from the
7600/6600 which were 60-bit machines (a change also planned for the
8600). Addressing was 24-bit, for a maximum of 1 megaword (8 MB) of
main memory. Memory was spread across 16 banks, each with a 50 ns
cycle time, allowing up to four words to be read per cycle.
