I remember a similar product here in the UK called the Philips Electronic
Engineer Kit. I had hours of fun with it in the early '70's. The only
transistors I remember were BC548's mounted on small PCBs which depressed
the spring contacts and were held in place when other components were added.

But now I try to remember which transistors they were, I not so sure about
the BC548 bit. Childhood memories can be very unreliable!

I vaguely remember it. Norelco is a Philips trade name, it seems to be
used now for their shavers in the US. It probably used Mullard devices
(Mullard was taken over by Philips).
