Well, I can remember the days of 405-line TV here in
England. We watched it on a valve set made by Pye (now
part of Philips). By the time of the Moon landings we had
dual-standard 405/625 and VHF/UHF sets. Oh, and BBC 2 was
a new channel on UHF, 625-line only!

I started in electronics with PNP germanium transistors,
although a lot of valve radio and tape recording gear was
still around. My idea of "high-tech" shortly after that
was a 741 op-amp.

I've just done a lecture where I showed people an
acoustically-coupled modem (300 baud). I had to take an
old phone along to show how it would fit, because no-one
would imagine that now, with all phones being different
