I however wire-wrapped it and used some 8x8kBit (or 2x8K) memory. Did add some extensions but never got to an eprom or cassette player extension. So every time I played with it, it was binary data input again
My older brother had the Phillips kit with the spring breadboard, but wasn't really into electronics - I so wanted that kit!
(The AM radio used to squeal if you touched the coil)
Most of my early electrical experiments were with old telephone relays and selectors salvaged by my grandad from Strowger exchanges, used to automate sections of our model railway.
Boy this brings back memories. These were called “Fox hole radios” invented back in the war.
My uncle introduced it to me back then, he was in the war.
You could get AM radio stations.
“ One common type was made from an oxidized razor blade (rusty or flamed) with a pencil lead pressed against the blade with a safety pin. The oxide layer on the blade and the point contact of the pencil lead form a semiconductor Schottky diode . . .”
My first electronic project was a 2 transistor AM radio that I built in Science class in high school around 1966. But I really hooked when I discovered digital electronics in the early '70s. Big thanks to Don Lancaster author of the TTL Cookbook.
My dad introduced me to Alfred Morgan's "A Boy's First Book of Radio and Electronics" in the late 60's. My first project was this radio from that book:
I still have the spool of magnet wire...

PS: Wiki says..."Morgan had four sons, which is why his books were originally written for boys, but editions from the 1970s were edited for boys and girls."
