Does anyone here remember what was the precursor
to the Philips Radionic series?

I had the Philips Electronic Engineer kit, then, later, the add on kit.
There were similar kits by Tri-ang, then the Inventor series which was
made by Lionel (the train people) in the US, and sold here by Tri-ang
under licence. I had the Bell telephone kit. All good fun at the time,
but no real long term interest.

On the other hand, I still have, and use, Bayko, Meccano, Dinky and
Hornby Trains. Rather more now than I received as a child :-)
