To me the interesting thing wasn't the retro technology, there have been Tv programs covering this before. For me it was the relationship the children of the family had with the technology. They expected things to just work and had no concept of programming the machine. As a kid, nearly everyone knew a few lines of basic or C, knew their bits and bytes etc. This is of course progress; the machine interacts with you on your level rather than you its.
It was however fascinating to see how the lad took to programming the BBC micro the way he did. I remember being just the same. Oh and the arguments with dad over the computer and monopolising the TV.
Now I have a z10 to play with (err, no that's "work"), none of your mickey-mouse PCs or Macs for me.
I don't remember TVs and VCRs being that unreliable though. Our GEC colour lasted from 1971 to 1985 and we only ever had 2 VCRs in 2 decades (first one wore out).
