The 75 in1 electronics kit. I had one of the range, but for the life of my can’tt remember which one. The 75 looks very familiar. I remember doing one from the book that was a long distance listening bug. You could hear people talking on the other side of the house. Never got the radio to work though.
My dad worked for Radio Rentals back in the 1970s. We were the first in the street to have colour TV and later the first to have a video recorder. I remember one Xmas he brought home a video camera on lone. It looked like a 8mm cine-camera with a cable attached to a shoulder strapped video recorder. As kids my brothers and I were amazed.
Activision games console too. Like an Atari but with crap games.
