When I was little I used to watch a TV series, not quite regularly, but it managed to stick in my memories. The problem is I can't remember the title.
It was done probably in the 90s, but I'm not sure about this. However, something that can help figuring this out, is that it was about a man guided by another man with a sort of calculator and a cigar.
This "guide" called his calculator with a weird name, something like Ziggie, but I cannot remember the exact name. Anyway, this series was peculiar because of this guide, who, if I'm not mistaken, could walk through obstacles.
Does it ring any bells?
