Some info on HAL
Here's some facts on HAL9000:
HAL was born at the H.A.L. lab in Urbana, Illinois on January 12, 1992. (Some fans disputed it and believed it was actually 1997, which is when they had their big birthday celebration for HAL... and Apple was one of the attendees.)
HAL stands for "Heuristically programmed ALgorithmic computer."
And lastly, each letter in "HAL" is only one letter away from "IBM". 😀 They claimed it was a coincidence, but IBM wasn't too happy about a "psychopath" computer allegedly symbolizing their supercomputers of the time.
I, like probably many others, have named all my Macs over the years HAL9000 and have themes to match. If you haven't seen the movie, I encourage you to see it.
