What was the hardware that makes up HAL9000 in the spaceship Discovery One, from Arthur C Clarke's 2001 series?
Wikipedia says that HAL became operational on 12 January 1997 and the books say 1992 and 1991. This would have been the age of the desktop PentiumMMX, and the 486 respectively.
The question was inspired by the last paragraph in this answer on Space Exploration.
I suspect this question cannot be answered, we can only conjecture.
