My favourite of these interstitial shorts was something called Computer-Home - or as we called it, Spider Chip 68000 - a bit of French computer animation that came out of nowhere, as far as we were concerned. And it wasn't ever online that I could find, until my housemate found it on one of his old VHS tapes!
So of course I ripped it and put it on YouTube:
But! I did that a year ago. The NEW surprise is that somebody else has posted the original French version!
And it's a much better transfer, even if you don't speak French. :D
So now you can relive your 1990s Doctor Who on KBTC fandom. Enjoy!
