Almost every house I've ever been in has an XOR gate wired up out of
light switches. ;-)

I got as far as buying about 20x 7400s before I realised I couldn't make
them do anything.
Good luck. 0;-)

Did you have to wait several minutes for the tubes to warm up? Turn on the

No. I'm not *that* old. :-P
Although, come to think of it... when you turn the TV off, it makes a
weird crackling noise, and the whole screen is now covered in static. I
never did understand why. Modern CRTs don't seem to do that...

When you get to the level of a Hawking or similar, it's not necessarily
staring at a piece of paper, it's working through things on the
whiteboard. That can be fun to watch - people at that level tend to
think out loud.

I saw that, but I didn't think it had any relevance to the conversation.
You mean to tell me the post office controls the phone system?
