I remember watching a TV show in the eighties - either a standalone movie or an episode of a series, I can't be sure which. The plot was about a young boy (teenager or late preteen) who was a genius with computers. He manages to make his computer do amazing things.
Sadly, his young life is cut short by illness. But he leaves a curious legacy for his computer-naive sister to find: a very long program (apparenly in BASIC, from what I recall - I used to program in this language, and I think I identified some of the commands and syntax as being BASIC) with instructions to key it into the system.
She diligently sets about typing the entire program into the system - very slowly ("hunt and peck") at first, then getting really efficient with the entry as she becomes more familiar with the QWERTY keyboard. Her ramp up in speed is meant to show the passage of time (because it's a really long program!).
When she finally executes the code, she is astonished to find that, somehow, her late brother's consciousness has been resurrected in the PC. If memory serves, the PC even talks to her in a typical (retro) computer-synthesised monotone.
I guess this vastly predated movies like Transcendence, with a broadly similar theme. It would be great if someone can help me identify this. Thanks in advance.
